Dyson - The technology and inventor company DYSON revolutionized vacuum cleaner technology, which had remained practically unchanged since 1901. Company founder James Dyson developed the Dyson bagless vacuum with constant suction because he was frustrated with his traditional vacuum becoming clogged and losing suction. Since then, the DYSON company has stood for the development of completely new technologies and products such as the Dyson Airblade hand dryer, which dries wet hands twice as quickly as conventional hand dryers, hygienically and without the use of heat, and the Dyson Air Multiplier fan, which works without rotor blades and has an even flow airflow generated. Today, Dyson employs more than 4,400 people worldwide, more than a third of whom are engineers and technicians. For DYSON, the environmental compatibility of its own products is a core concern. However, Dyson is not primarily aiming to launch models that can be described as 'green'. Rather, the focus is on efficient engineering work ? achieving more with less. Dyson engineers have developed vacuum cleaner motors that achieve maximum performance with lower wattage. And with better cleaning results than most other vacuum cleaners with more powerful motors.

Electric door opener - Are you planning the access system for your building and need an electric door opener for it? You will find the right components for this in the eibabo® shop. Choose from numerous variants from different manufacturers and also find out what types of door openers are available and what you should pay attention to when buying.What are electric door openers?The term 'electric door opener' conceals very different ideas about which products are actually involved. As part of our customer service, our customers mainly ask about three product groups:Drives for doors and gatesThere are different types of drives for doors and gates. The simplest type is the classic door operator, which lifts a garage door, for example. This usually consists of an electric motor with a movable linkage, which opens and closes the gate. Alternatively, this type of door opening is also available with a chain drive. There are openers with linear drives and lever drives for gates on property boundaries and driveways. The linear actuator design includes an elongated body in which the gear box is enclosed. The gearbox turns a worm drive, causing a rod attached to the gate to lengthen or shorten. This opens or closes the gate. The design of the lever drive consists of a classic housing in which the gear is located. The power of the gear is transmitted to a steel lever attached to the gate leaf. This enables the gate to be opened and closed. In this construction, there are right and left mechanisms.Electromechanical door leaf openerOne of the biggest challenges for people with walkers or wheelchairs is getting through doors. Sitting in a wheelchair and opening a door at the same time is a problem. Likewise, closing a door after driving through it is difficult. To master this challenge, there are electromechanical door leaf openers. Surely you have seen these in hospitals, shops and offices before. These are usually activated by stepping or driving on a mat, or by walking past an electrical sensor. However, these devices are quite expensive. Of course, there are also simpler models for private use. Residential electric door openers consist of an electric motor mounted on the door frame or the door itself. The motor activates and moves a rod that opens and closes the door. The electromechanical door leaf opener can be installed on either interior or exterior doors.Electrical or electromagnetic door lock openersA modern door lock is a mechanism that can consist of a complex combination of locking devices. The safety of property and personal safety depend on the reliability of the lock or the locking mechanism and its quality. Therefore, you should plan your purchase with all due care. Electrical and electromagnetic openers and closers are often used for controlled locking and unlocking of doors in access control systems and management systems. Unlike electromechanical models, these systems are:easy to handlequickly mounted on the doordurableinexpensive  TIPIn this eibabo® catalog you will mainly find products from the area of electric and electromagnetic door openers. Automatic door openers are ubiquitous in apartment buildings, industrial plants and large office buildings. These unlock or lock the lock at an entrance by an electrical or electromagnetic process. When and how a door is locked or opened depends on the installation of the door opener. If a door opener works with quiescent current, the door only opens when the circuit is interrupted. This is typically the case with escape doors. However, there are also working current door openers. These only open a door when power is applied. This means that in the event of a power failure, the corresponding door would remain closed. Whichever type you prefer, you can get high-quality electric door openers at reasonable prices in the eibabo® online shop. Manufacturers of safe and well thought-out systems are Assa Abloy effeff, Berner gate drives, Etherma, Geze, Grothe, Novar, Siedle and Viveroo. Pay securely and monitor your delivery with our track-and-trace system.Typically, electromagnetic locks hold doors closed due to the action of a powerful electromagnet. This attracts a metal plate attached to the door. The door is opened using the exit button, which changes the state of electromagnetism. Alternatively, this control signal can also be triggered centrally by the access control system.Image: Assa Abloy effeff 118WR-------B71 electric door openerWhat types of electromagnetic door openers are there?Due to their design, electromagnetic door openers differ in models whose contact either 'shears off' or 'tears off'. This depends on the position of the contacts in connection with the opening direction of the door. Furthermore, one subdivides into add-on locks and built-in locks. Electromagnetic attachment locks are the most common, as they do not affect the structure and stability of a door leaf. Since there are no moving and rubbing parts in this type of locks, their function is guaranteed in all climatic conditions. Within access control systems, electromagnetic door openers are often used for external doors of residential buildings, offices, industrial buildings, supermarkets with normal security requirements.How do electromagnetic door openers work?An electromagnetic lock consists of 2 parts:an electromagnet mounted on the door framea metal counter plate which is attached to or in the door In the so-called normally open operating mode, a direct current or alternating current is supplied to the electromagnet winding in order to establish a strong magnetic field. This pulls the metal plate of the door towards the lock. The door is held closed by the force of the magnetic field. To open the door, the circuit must be broken. The magnetic field disappears and the door can be opened. Even in the event of an unplanned power failure, the electromagnet releases the plate and the door goes into the unlocked state. Therefore, not only electromagnetic locks are installed on the most important doors, but also conventional mechanical or electromechanical locks.TIPModels are available that work on the opposite principle - i.e. are closed without current. In these cases, the magnetic field is established without current and the door is closed by default. The magnetic field is only interrupted when a voltage is applied and the door can be opened.This functional principle is very common in classic door openers, for example.How securely do electromagnetic door locks close?All electromagnetic locks have a high mechanical traction or holding power. This is given in kilograms. The heavier and more important a door is, the higher the holding power of the lock should be. When choosing a model that suits you, you can use the following rule of thumb:A holding force of 150 kg or more is usually sufficient for interior doorsElectromagnetic locks with a holding force of 300 kg or more are usually used for standard street doorsFor security doors and heavy steel doors, use models with a pull force of over 1000 kg What are the advantages and disadvantages of electromagnetic door openers?Advantages over other locks and locking mechanisms include ease of installation and durability. There are no mechanically moving parts that can wear out or jam. Compared to electromechanical door openers, the power consumption is low. Magnetic door locks are insensitive to heat, cold and precipitation and can be used in rooms with high humidity. Their dependency on electricity can be seen as a disadvantage.What should be considered when buying electromagnetic door openers?We have already mentioned many properties that limit the choice according to your needs. Before you buy, consider the following points, among others:Should it be a built-in device or a surface-mounted device?Should the opener work with open-circuit current or with closed-circuit current?What type and level of power supply is required?Is the design decisive (left / right / symmetrical)?Does compatibility with existing mortise locks and striking plates have to be guaranteed?Do you want manual locking or unlocking for emergencies?Is one opener enough or should it be a set with strike plate and frame?What holding power should the device have? What is the difference to a purely electric door lock opener?Electromechanical door locks are also available on the market. These are mechanical locks with electronic components. These door openers are also powered and work in combination with a classic locking mechanism to lock or open the door. The type of locking and unlocking can vary. These can be buttons, keypads for entering codes or passwords, biometric devices, scanners, key fobs or key cards.  Catalogue content:In this eibabo® catalogue Alarm installations, emergency call and signalling > Electrical door opener you will find items from the following product groups:Item overview:Angled locking plateAutomatic staircase lightCable transitionCable transitionsCone contactDetentDoor opener coilInlet reed contact bracketLockingLocking plateMortise door openerMounting casePush-on boltReplacement plateSecuritySecurity lock openerSliderSpacer plateStandard door openerSwing gate operatorUniversal door openerUnlockingfrom the following manufacturers:Manufacturer overview catalogue Electric door opener:Assa Abloy effeffBerner TorantriebeEthermaGezeGrotheNovarSiedleViveroo
Reflection light barrier - James Bond says hello! Surely you have already seen in various crime or agent films how the use of fog or powder makes the rays of an infrared light barrier visible in order to be able to circumvent an installed security system. However, the hidden monitoring of premises is only one of many tasks that light barriers can take on. Basically, a light barrier is an optoelectronic sensor that monitors a certain standard condition using light beams. If the light beam is interrupted and the normal state is changed, the sensor triggers an electrical signal. In addition to the classic light barriers, in which the transmitter and receiver are installed separately from each other and establish a light beam in between, the transmitter and receiver are installed directly together in a reflective light barrier. The light beam is sent back from the transmitter to the receiver via a remotely mounted reflector. Whatever switching and signaling processes you want to trigger with a photoelectric reflex switch, you can get high-quality products with precise and modern sensor technology here in the eibabo online shop.Catalogue content:In this eibabo® catalogue Sensors > Reflection light barrier you will find items from the following product groups:Item overview:Complete light barrierCuboid light barrierDC light barrierDiffuse buttonLight barriersLight curtainPhotoelectric barrierPolarizationReflection light barrierReflection systemReflex light barrierRetro-reflective sensorRetroreflective photoelectric sensorSafety-related photoelectric reflex switchThread light barrierTwo-way light barrierfrom the following manufacturers:Manufacturer overview catalogue Reflection light barrier:Ifm ElectronicLeuzeOmronPepperl + FuchsRockwellSchneider ElectricSickWenglor

Patch cables copper - Patch cords are cable types used in telecommunications and network technology. They are used to connect, network or distribute telephone systems or Internet installations within buildings or from a central location. Patch cords are available in copper and fiber optic versions. The cores of the copper patch cables consist of flexible copper strands. Fiber optic patch cords, on the other hand, consist of two separate optical fibers. But what does patching actually mean? Patching is the connection of ports, i.e. the corresponding connection points from one patch panel to another or to network devices such as computers, televisions, routers or switches. This makes it very easy to set up a network of end devices that communicate with one another. In the eibabo online shop you can get Cat5 and Cat6 patch cables at reasonable prices. This allows you to transfer data at high speeds within your network.Catalogue content:In this eibabo® catalogue Data and telecommunication > Patch cord copper (twisted pair) you will find items from the following product groups:Item overview:CableCAT 5 patch cordCat 6A patch cordCAT 7 patch cordComputer cableConnecting cableConnecting cordConnecting pipeConnection cableCopper cableData cableEthernet patch cordExtension circuitISDN patch cordLineMade-up data cableManagementMedia couplerNetwork cablePatch cablePatch cable copper (data cable)Patch CordPatch cord copperPatch cord copper (twisted pair)PC cablePhone cordReady-made cableWestern jackfrom the following manufacturers:Manufacturer overview catalogue Patch cables copper:3MAssmannBachmannBrand-RexCommScope EMEACommScope/AMP NetconnCorningDehnDätwylerDätwyler IT InfraE+P ElektrikEatonEFB-ElektronikHagerHartingHeliosHighpatchHomewayLappLeoni DatacomLingg & JankeMertenMetzMobotixPanduitPhoenixPilzReichle & De-MassariRutenbeckSchneider ElectricSiemensTehalitTelegärtnerTeleg?rtnerWantecWeidmüllerWentronic
Through terminal - Which feed-through terminals should you use for your control cabinet? Are terminal blocks the same as feed-through blocks? Find out here what the differences are between feed-through terminals and what they are used for. In the eibabo® technology store you can get feed-through terminal blocks from all well-known manufacturers such as ABB, Eaton, Eberle, Hager, Metz, Phoenix, Schneider Electric, Siemens, Spelsberg, TE Connectivity, WAGO, Weidmüller, Wieland and Wöhner at great prices and in large quantities. We deliver our range worldwide.Feed-through terminals fulfill several functions and are among the most important components within a control cabinet. It is mounted on the DIN rail. Feed-through terminals are connecting elements between the incoming cables and lines of an installation and the actual control cabinet installation.What is the difference between feed-through terminals and terminal blocks?Feed-through terminals are terminal blocks. 'Terminal block' is a generic term that also includes other types of terminals. These include, for example, fuse terminals and relay terminals. Other terms describe the way a terminal is constructed or its ability to connect the conductors. In these contexts, one often hears about one-tier terminals, three-tier terminals, spring-loaded terminals, push-in terminals or screw terminals. We would like to briefly discuss some of these types in the following sections.Why are feed-through terminals indispensable components in the control cabinet?Feed-through terminals offer the necessary flexibility in the control cabinet to connect rigid incoming cables and lines to the relevant fuses, actuators or other devices. A direct connection without feed-through terminals does not make sense. A clear installation would not be possible. First, the cables and lines are clearly laid out on the terminal blocks. They then lead them from there to the devices in the control cabinet. As a result, the entire installation remains flexible because there are connection points and nodes for checking and changing the system structure.Image: Phoenix PT 2.5-3L feed-through terminalEach connection that is made takes on a function previously defined in the circuit diagram. The installation of the system and the function of individual connections remains traceable. This makes later additions, repairs and maintenance easier. If you want to make changes, these can be done by reconnecting individual wires. The rigid supply lines remain unaffected.And there are other advantages: For example, you can only connect two wires to many modular installation devices. The feed-through terminal blocks offer further advantages here. An example: A fuse is intended to protect several lines. However, you can only connect the cores of one line. In order to also integrate the other lines, you can create clear bridge connections on the feed-through terminals. The electrician can also carry out insulation measurements and other control work directly on the terminal blocks. Troubleshooting is made much easier and faster.What different feed-through terminals are there?Each manufacturer builds the feed-through terminals slightly differently. However, the principle is the same. There are single-level terminals and multi-level terminals. While you can only connect one line in the single-level terminal, several incoming and outgoing lines can be installed in multi-level terminals. Use a three-tier terminal for a three-wire cable. The is designed for connecting the protective conductor, the L conductor and the N conductor. This arrangement saves an enormous amount of space in the control cabinet. Three-tier terminals are mainly found in the control cabinets of private households and in smart home installations. TIP:On some models, the protective conductor has no connection point for the outgoing line. The protective earth contact is made directly by the clamp connection with the DIN rail. Another feature that distinguishes feed-through terminals is the way the wires are fastened. The screw terminal fixes the respective wire with a screw connection. This method takes a comparatively long time, especially when the plant is complex. A spring-loaded terminal makes electrical contact with a mechanical spring. This consists of a bent, flat copper contact. The wire must be inserted through a hole in the copper contact. This is only possible if the contact is clamped with a pointed tool. When the clamping tool is removed, the spring pulls back and the wire is jammed. The connection is released in the same way. The push-in connection is another fastening variant, similar to the spring-loaded terminal. Here, too, a spring presses against the wire. In contrast to the spring-cage connection, installation is tool-free and therefore even faster. The wire is inserted into the spring shaft of the feed-through terminal and the spring locks automatically. If you want to loosen the connection, you need a pointed tool. A small screwdriver is usually sufficient, which bends the retaining spring to the side and loosens the wire. This method saves a lot of time with cores with solid conductors. Wires with flexible conductors can also be attached using wire end sleeves using this method.Solid and flexible veinsYou can connect cables with solid cores and flexible strands in feed-through terminals. Both variants and combinations are permitted. Flexible cores can easily fan out. The use of ferrules makes handling easier with spring connections.The attachment of the wire using cutting terminals is rather rare. Use this variant if your veins are particularly thin. Here, the contact is made through a small cut in the insulation.Depending on the function and area of application, cables and wires with different cross-sections are used in the electrical installation. This affects the feed-through terminals. Appropriate feed-through terminals are available for all common cable cross-sections. Whether a clamp can be used for a specific cross-section is indicated on the clamp. It is usually possible to bridge the L conductor and the N conductor using several feed-through terminals, sometimes on several levels. Suitable cable bridges are available here in the shop.markLabeling the lines helps with orientation, especially when a new employee or another electrical company takes over the system. Some terminals have labeling fields. We recommend using this option and labeling all devices and connections in a meaningful way.The design of the neutral conductor contact is another distinguishing feature. In addition to models for classic wiring, there are feed-through terminals with which an N busbar can be used. The neutral contact on these terminals is designed accordingly so that the connection can be made with one hand. When using a busbar, you need an additional terminal for feeding. To securely fix the rail, use suitable support blocks or the fastening levers on the end clamps at the beginning and end of the row. Longer rails are additionally fixed every 20 cm. To be able to use cables with five cores, use multi-level terminals to connect the outer conductors.How to use feed-through terminals in the KNX area?In addition to the classic feed-through terminals, you can get special terminal blocks for low-voltage or KNX use. These have a different color and can therefore immediately be distinguished from other terminal blocks. This also contributes to order and clarity in the control cabinet. In terms of function, these terminal blocks hardly differ from conventional terminal blocks. You can connect cables with a cross-section of up to 1.5 mm2 to these terminals.Why are feed-through terminals not closed on one side?The available space in the control cabinet is specified in modular widths (HP). These provide information about the capacity of a control cabinet. Feed-through terminals are not manufactured according to this pitch, but as narrow as possible. The narrower a terminal, the more terminals can be installed on a specific area of the DIN rail. Good to know:Feed-through terminals are not closed on one side. The missing cover saves a little space. In relation to the length of a top-hat rail, more terminals can be mounted. Since feed-through terminals are mounted directly next to each other on the DIN rail, there is no danger of touching the contacts on the open sides. Without a side cover, a terminal is narrower. A cover is only attached to the last terminal in a row.Which installation aids and which accessories are available for feed-through terminal blocks?For the construction of a control cabinet, you receive numerous well thought-out components that simplify your work. For feed-through terminals, for example, the cross-bridges and busbars already mentioned are available. In addition, you will receive separator plates and end plates, covers, feeds or end blocks as well as test plugs, fuses, labeling fields and other components.  Catalogue content:In this eibabo® catalogue Terminal blocks > Feed-through terminal block you will find items from the following product groups:Item overview:Base clampBolt clampChangeover relayCompartment clampConnecting combsConnection moduleConnection technologyDistribution blockFeed terminalFour-level clampLightning arrowMarshalling boxMini clampMotor connection terminalMotor output terminalMulti-level clampMulti-wire terminalNeutral terminalPotential clampRelay terminalSocketSpring clampsSpring clipSwitching relayTerminal block connectorThermal voltage terminal blockThrough terminalUniversal clampfrom the following manufacturers:Manufacturer overview catalogue Through terminal:ABBEatonEberleHagerMetzPhoenixSchneider ElectricSiemensSpelsbergTE ConnectivityWAGOWeidmüllerWielandWöhner
Protective conductor terminal - You take care of the structure of your control cabinet and use various terminal blocks to organize your electrical installation. If you are still missing protective conductor terminals to complete your system, then you have come to the right place in this catalog from our shop. Here you can get all common variants from well-known manufacturers at top conditions. Protective earth terminals belong to the series terminals and were developed for electrical distribution installation. These are capable of accommodating fine-wire, multi-wire or solid conductor cross-sections. Cables with attached ferrules can also be installed in protective conductor terminals.What is a protective conductor?The protective conductor or PE conductor (PE stands for protective earth) is primarily used to connect the masses of electrical devices and conductive elements to earth. The protective conductor is easily recognizable by its green-yellow color.Already knewThe nationwide establishment of the protective conductor in Germany, Austria and Switzerland took several decades. More than 50 years passed from the first proposal to introduce a 'neutral conductor' around 1914 to the uniform definition of the green and yellow marking in 1965.An example: Let's take the classic NYM-J 3x1.5 mm² sheathed cable. Two wires carry current here, the one with the blue insulation and the one with the brown insulation. The third wire is the green-yellow protective conductor, which normally does not carry any current. If a current-carrying phase touches a metallic housing, a so-called residual current flows through it. If there is no protective conductor, the housing is not grounded and the residual current cannot flow. If a person touches the housing, the current is returned to earth via their body. This not only results in an unpleasant discharge, but in some cases leads to burns or, in extreme cases, to an electric shock, which can lead to cardiac arrest. However, if a protective conductor is properly installed, the enclosure is connected to earth through it. The residual current can thus flow off via the protective conductor.In the control cabinet, the incoming protective conductors are sorted and fastened via protective conductor terminals.What is a terminal block or a feed-through terminal block for protective conductors?Terminal blocks fulfill several functions and are among the most important components within a control cabinet. It is mounted on the DIN rail. In general, terminal blocks are connecting elements between the incoming cables and lines of an installation and the actual control cabinet installation. Technically, the special protective conductor clamps do not differ from the clamps for external conductors or neutral conductors, but they are specially designed to accommodate the green-yellow protective conductor. TIPMany ground terminals also have a coloured, mostly green-yellow housing. Their purpose is therefore unmistakable and the terminals in the control cabinet can be recognized as such at first glance. Feed-through terminals are also often mentioned. 'Terminal block' is a generic term that also includes other types of terminals. These include, for example, fuse terminals and relay terminals. Other terms describe the way a terminal is constructed or its ability to connect the conductors. In this context one often hears about one-tier terminals, three-tier terminals, spring-loaded terminals, push-in terminals or screw terminals.Why should I use protective conductor terminals?Feed-through terminals for protective conductors are required connecting elements in the control cabinet between the rigid incoming cables or lines and the following control cabinet installation. These offer the necessary flexibility to connect the protective conductors to the end devices easily and clearly. A clear installation would not be possible without the feed-through terminals. In practice, the incoming cables and lines are clearly laid out on the terminals and the individual wires then lead from there to the devices in the control cabinet. This keeps the entire installation flexible. There are connection points and nodes for checking and changing the system structure.Image: WAGO 2002-3207 three-level terminalEach protective conductor connection that is made assumes a protective function specified in the circuit diagram. This means that both the installation of the system and the function of individual connections are always traceable. This makes later maintenance, additions or repairs easier. Changes are possible at any time by reconnecting individual lines. The rigid supply lines remain unaffected.What is the difference between protective conductor terminals?Each manufacturer builds the protective conductor terminals slightly differently. However, the principle is the same. There are single-level clamps and multi-level clamps. While you can only connect one protective wire in the single-level terminal, several incoming and outgoing lines can be installed in multi-level terminals. A multi-level arrangement saves an enormous amount of space in the control cabinet.Another distinguishing feature is the way the wires are attached. With a screw terminal, the respective wire is fixed with a screw connection. This method is comparatively complex and takes a lot of time. Especially when the system is complex, you save a lot of time by using a spring-loaded terminal. This variant makes the electrical contact using a spring. The spring usually consists of a bent, flat copper contact. The protective conductor must be inserted through a hole in the copper contact. This is only possible if the contact is clamped with a pointed tool. When the clamping tool is removed, the spring pulls back and the protective conductor is jammed. This connection is released in the same way. Push-in mounting is another connection variant. This is similar to the spring-loaded terminal. But unlike the spring-loaded connection, installation is tool-free and therefore even faster. The protective conductor is inserted into the spring shaft of the terminal and the spring locks automatically. You need a tool to loosen the connection. Bend the retaining spring to the side with a small screwdriver and the protective conductor can be loosened. This method saves a lot of time, especially for cores with solid conductors. The use of ferrules is recommended for cores with flexible conductors (strands). Fastening the conductors using insulation displacement terminals is rather rare. Use this variant if your conductors are particularly thin. Here, the contact is made through a small cut in the insulation. Cheaper in a setProtective conductor terminal blocks are available individually or in sets of 25, 40 or 50 at an attractive price advantage. The cross-section of the protective conductor also affects the protective conductor terminal. Here in the shop you can get the right protective conductor terminals for all common cable cross-sections. Whether a clamp can be used for a specific cross-section is usually stated on the clamp.Why are protective conductor terminals not closed on one side?The space in a control cabinet is almost always tight. The storage capacity of a control cabinet is generally specified in module widths (HP). Protective conductor terminals are not manufactured according to this grid dimension, but as narrow as possible. The width is determined by the design of the electrical connection and the cable cross-section. Since the terminals are mounted directly in line, there is no risk of touching the contacts on the open sides. Without the second side cover, a terminal is slightly narrower. A cover is only attached to the last terminal in a row. The narrower the individual terminal is, the more terminals can be accommodated on a specific section of the DIN rail.You can buy protective conductor terminals quickly and cheaply in the eibabo® technology store ? your competence center for smart homes and electrical installations.

Circuit breaker - Are you sure that your electrical installation offers correct protection against overcurrents? Errors in protection can have dangerous consequences. Read here what you should pay attention to and the importance of the high-quality miniature circuit breakers from our eibabo® online shop.The use of electronic devices is a matter of course for us. Their use is comfortable and safe. But what happens if the television, washing machine, oven or refrigerator has a short circuit or overcurrent? These devices would be permanently damaged and fire accidents would be the result if suitable protective mechanisms were not activated as quickly as possible. In everyday life, hardly anyone thinks about these dangers. Why is that? Various safety elements are integrated in today's electrical installations, which protect people, electrical devices or the circuits themselves from damage caused by overcurrent. Modern miniature circuit breakers, among others, perform this task. They are also called circuit breakers or fuses. Do you remember?Historically, fuses contained a metal wire or strip that would melt if overcurrented, interrupting the flow of current. As a result, a tripped fuse was destroyed and had to be replaced. These so-called safety fuses are still used today, for example in vehicle construction. Circuit breakers work differently, can be reactivated manually after tripping and thus offer obvious advantages over fuses.What are circuit breakers?All non-adjustable circuit breakers are referred to as miniature circuit breakers, also known as MCBs. MCB is the abbreviation for the English term 'Miniature Circuit Breaker'. It is always an overcurrent protective device in the electrical installation when used in low-voltage networks. Miniature circuit breakers protect lines from damage caused by heating up as a result of excessive current, usually caused by a short circuit. The miniature circuit breaker is a reusable safety element that does not reset itself automatically. This makes handling very safe and you can quickly restore the power supply after it has been triggered. There are no high maintenance and replacement costs. Combinations of a miniature circuit breaker (MCB) with a residual current device (RCCB) are also available, these combined devices are referred to as RCBO devices (English: 'Residual current operated Circuit-Breaker with Overcurrent protection').What were the different miniature circuit breakers developed for?The miniature circuit breakers available from eibabo® differ not only in their rated current and design, but also in their tripping characteristics. The following standardized tripping characteristics are currently permitted for miniature circuit breakers:Type B (standard line protection)Type B miniature circuit breakers are the usual variants for private use. These switch off the circuit as soon as the current exceeds three to five times the actual current flow. Type C (higher inrush current for machines or lamp groups)Type C switches are used, among other things, in household appliances and in commercial devices such as fluorescent tubes, PCs, printers and servers. These break the circuit when the current exceeds five to ten times the actual current flow. Type D (for highly inductive or capacitive loads, e.g. with transformers, magnets or capacitors)Type D MCBs offer high resistance. These turn off the circuit when the current exceeds ten to twenty times the actual current flow. Type E (SLS / circuit breakers for main lines)SLS stands for 'Selective Circuit Breaker'. This triggers with a time delay when the current exceeds 5 to 6.25 times the actual nominal current. This means that downstream fuses or classic miniature circuit breakers switch off the current beforehand. Type K (with high inrush current with sensitive overload tripping)Type K miniature circuit breakers trip at eight to twelve times the actual current flow. These protect heavy-duty equipment such as compressors, winding motors and X-ray machines. Type Z (semiconductor protection with high line impedance)Type Z miniature circuit breakers are sensitive to short circuits and are used in semiconductor production. These break the circuit when the current exceeds two to three times the actual rated current. Image: Hager MCN316 miniature circuit breaker 3-poleIs the installation of miniature circuit breakers absolutely necessary?Miniature circuit breakers for lighting circuits and socket circuits are mandatory in the circuit distributors of apartments and residential buildings. You must install these. For industrial installations, in industrial plants and in trade, please pay attention to the higher requirements for miniature circuit breakers. Here, miniature circuit breakers / MCBs often also protect equipment and devices.How does a circuit breaker work?Miniature circuit breakers usually have two trigger mechanisms, the electromagnetic quick release and the thermal release. When an overcurrent flows through the circuit breaker, a bimetallic strip in the thermal trip unit heats up and bends. This triggers an interlock, interrupting the flow of current in the circuit. This process protects against hazards or damage to devices that can result from the overload. In addition, the melting of the lines is prevented. In the event of a short circuit, the electromagnetic trigger acts. Here the current suddenly increases and a magnetic field builds up inside a coil. A bolt reacts to this, hitting the trigger mechanism in fractions of a second and interrupting the circuit.NoticeIn the circuit breaker, the outer switching lever is not directly connected to the actual switching mechanism. The device also triggers reliably if the shift lever is jammed, locked or manipulated.To get the current flow going again, the circuit breaker can be reactivated using the shift lever.What is the difference between single-pole and multi-pole miniature circuit breakers?You use single-pole miniature circuit breakers, for example, for circuits with single-phase alternating current. Three-pole miniature circuit breakers are used in AC circuits with three current-carrying phases. In the event of an overcurrent or short circuit, these are able to switch off all phases. This happens even if the fault affects only one phase. recommendationWe advise you to protect multi-phase circuits with a multi-pole circuit breaker. Do not divide the individual phases into single-pole circuit breakers. Working with electricity is dangerous. Please have changes or extensions to your system carried out by a specialist electrician.Which miniature circuit breakers are recommended?A large selection of miniature circuit breakers for electrical distribution installation can be found in the eibabo® online catalogue. We carry high-quality and reliable miniature circuit breakers from well-known and well-known manufacturers such as Siemens, ETA, ABL Sursum, ABB Stotz S&J, Eaton, Hager, Schneider Electric or from Moeller, Doepke and Stahl.  Catalogue content:In this eibabo® catalogue Circuit breakers and fuses > Miniature circuit breaker (MCB) you will find items from the following product groups:Item overview:AC circuit breakerAC voltage machineAuxiliary circuitBuilt-in deviceBuilt-in distributor deviceBuilt-in machineBusbar automatBusbar fuseCable circuit breakerCircuit breakerControl circuit breakerDC circuit breakerDC voltageDirect currentDirect current machineEnergy TechnologyHigh performance circuit breakerInstallation machineMCB circuit breakerModular installation deviceMotor protection switchOvercurrent protectionOvercurrent switchPlug-in circuit breakerRail mounted devicesScrew circuit breakerShort circuitTax securityfrom the following manufacturers:Manufacturer overview catalogue Circuit breaker:ABBABNBachmannDoepkeEatonETAHagerMurrelektronikPhoenixSchneider ElectricSiemensStahl
