Circuit breaker transf. protect. - By using a circuit breaker, you ensure that no increased inrush current flows when you switch on a machine or another electrical consumer. A circuit breaker for transformers also performs this task, except that it is tailored to the corresponding needs of the transformer used in each case. But what does that mean? Transformers that can withstand high inrush currents usually work with high losses, which means they run hot. However, this can be critical if other components of the overall construction do not tolerate high heat dissipation. In contrast, low-loss transformers are not designed for higher inrush currents. To put it simply, this fundamental problem is due to the design of the respective transformer or the structure of its core. With high-quality circuit breakers from the eibabo online shop that are tailored to your installation, you can protect your transformers against short circuits and overloads. With an integrated control input, such a circuit breaker for transformers also functions as a relay for switching the device on and off.Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Power circuit-breaker for trafo/generator/installation protection you will find items from the following product groups:Item overview:AutomaticBasic switchBuilt-in deviceBuilt-in distributor deviceCircuit breakerCircuit breaker for cable protectionCircuit breaker for transformer protectionCircuit breakers for system protectionCircuit breakers for transformer, generator and system protectionDifferential currentGenerator circuit breakerHigh power switchManual operationMCCBMini circuit breakerModular installation deviceMolded case circuit breakerPower circuit-breaker for trafo/generator/installation prot.Power circuit-breaker for trafo/generator/installation protectionPower-cut-out switchSelective circuit breakerSelective protectionShort circuit protectionSlide-in technologySwitchSystem circuit breakerTransformer circuit breakerVoltage transformer circuit breakerfrom the following manufacturers:Manufacturer overview catalogue Circuit breaker transf. protect.:ABBEatonHagerMitsubishiRockwellSchneider ElectricSiemens
Residual current circuit breaker - Why should you never do without a residual current circuit breaker in your installations? And how do you find the right device with the best price-performance ratio? Interesting information about the function and use can be found on this page. Notice:Working with electricity is always dangerous. Always have electrical installations carried out by a specialist electrical company. If you're unsure as a layperson, be sure to invest in professional support. This way you get a working installation and can rely on the installer's warranty if necessary.What is a residual current circuit breaker?Residual current circuit breakers, also known as residual current circuit breakers, bear the official designation RCCB. This is an abbreviation for 'residual current operated circuit breaker' and the devices belong to the superordinate group of 'residual current devices' (RCD), i.e. residual current protective devices. Residual current circuit breakers prevent dangerously high residual currents against earth and thus help to prevent life-threatening electrical accidents in low-voltage networks. These are connected upstream of the overcurrent protection devices in circuit distributors.At eibabo® you will find not only a large selection of residual current circuit breakers, but also other protective devices such as residual current protective adapters, residual current protective plugs, automatic circuit breakers and automatic personal protection.Is an RCD and an RCCB the same thing?In colloquial German, the term 'FI switch' is still very common. The 'F' stands for error and the 'I' for the symbol for the current strength. Ultimately, it's just another name for the same device.Picture: Eaton PXF-25/2/003-A residual current circuit breakerHow does a residual current circuit breaker work?The device builds up a magnetic field around the incoming currents. This is neutralized by the currents flowing back. In error-free normal operation, this creates a balance between the energies within the system, which ensures that a relay can let the current flow unhindered. If a fault current occurs, it will create an imbalance, causing the voltage to drop across the relay and its auxiliary contacts to break the circuit. As a result, the switch shuts down the system within tenths of a second without auxiliary power.Is the use of a residual current circuit breaker mandatory?It all depends on which country you are in. There are national regulations for this. In Great Britain, the simpler and smaller electronic residual current circuit breakers are currently still common. In principle, however, the use of these devices is mandatory in many countries for new installations, modernizations or far-reaching changes for private households, commercial units and industrial plants in addition to the installed overcurrent protection devices.In Germany, this applies, for example, to socket circuits up to 32 A and lighting circuits in apartments as well as for commercial buildings, schools and training centers, baths and swimming pools as well as fire-prone business premises and systems. Notice:Old systems that corresponded to the applicable standards at the time of their construction usually have grandfathering. You may continue to operate, maintain and repair them, but not fundamentally expand or change them.i have backups Can I then do without the residual current circuit breaker?Irrespective of the fact that residual current circuit breakers are necessary for the technical acceptance of the system, they fulfill a different task compared to normal fuses and cannot be omitted. Normal home fuses are also known as circuit breakers. Their function can already be derived from this. They protect power lines from short circuits. They interrupt the circuit even at higher currents and imminent overload. This prevents cable fires, for example.Residual current circuit breakers, on the other hand, have the primary task of protecting people and switching them off as quickly as possible, for example if people touch the damaged part of a live line. Because that can be life-threatening. The switch is also used for fire protection. Small fault currents that do not trigger a normal house fuse are prevented.Which type of residual current circuit breaker is the right one for end users?There are very different models on the market, each with individual characteristics. A basic distinction is made between types A, A-EV, AC, B, B+, F and S. Type A is the most common variant for use in classic households, in commerce, in public facilities, functional buildings and industrial plants. This is a pulsating current-sensitive switch that detects alternating currents and pulsating DC residual currents. The value at which the switch should trip is 30 mA (milliamps) in normal use. It is therefore necessary to install a switch with a rated fault current of 30 mA.Rated current and rated residual current ? what is the difference?Both key figures are crucial for choosing the right circuit breaker. The rated current is the maximum voltage that can be conducted via the residual current circuit breaker per phase conductor. The rated residual current describes the maximum measured difference between incoming and outgoing currents before a residual current circuit breaker has to trip at the latest.AssemblyA residual current circuit breaker is typically installed in the meter cabinet / electrical distribution box. The position is directly behind the electricity meter and in front of the classic circuit breakers.The switch thus covers all circuits in a system, regardless of whether they are inside a building or outside. However, it is advisable to use several separate residual current circuit breakers and fuses depending on use. In many countries and regions it is even mandatory to equip special areas with their own residual current circuit breaker.Interesting - short and sweetAre additional protective measures possible?If you want to further increase the scope of protection of your electrical installation, you can equip personal protection sockets or socket strips with a residual current circuit breaker with a rated residual current of 10mA to 30mA. What additional protection do residual current circuit breakers offer?The special properties of residual current circuit breakers include personal protection against life-threatening currents and protection against fires that can be caused by earth fault currents, for example. How do residual current circuit breakers work?Due to the low tripping currents of 10mA to 500mA, the use of residual current circuit breakers means that the currents at the fault location are not as high. Are there performance differences in residual current circuit breakers?You can get the devices here in the shop in different versions: 16 A, 25 A, 40 A, 63 A and 100 A (ampere). The ampere rating of the device indicates the nominal current for which the residual current circuit breaker is designed and, along with the selection of the triggering rated residual current, represents one of the most important parameters in the purchase decision. Who Makes Reliable RCDs?We only carry high-quality devices from well-known manufacturers such as Siemens, ABB Stotz S&J, Doepke, Schneider Electric and Eaton (Moeller), Jung, Hager and ABL Sursum. Good to knowWhen choosing a residual current circuit breaker, please take its dimensioning into account. The circuit breaker must never be designed smaller than the upstream fuse, otherwise it will be overloaded.By the way: The forerunner of modern residual current circuit breakers is a German development from 1903. The principle of residual current protection goes back to a development by Sigmund Schuckert from Nuremberg, who had a corresponding device patented under the name summation current circuit for earth fault detection. The technology was then continuously further developed and in 1957 the Austrian Gottfried Biegelmeier presented the residual current circuit breaker in its current form.What effect does charging an electric car have on the residual current circuit breaker?Usually the purchase of an electric car has no effect on the circuit breaker. Nevertheless, care must be taken to ensure that protection against DC residual current is guaranteed during multi-phase charging. A type A circuit breaker does not offer such protection, but don't worry: plug-in hybrid vehicles typically charge in a single phase and are therefore technically hardly different from other household appliances. Pure electric cars that are capable of multi-phase charging cannot be connected directly to the house voltage. This requires either a wall box or at least a mobile charging cable with charging control, which then connects to a conventional 16A or 32A CEE socket. In both cases, the control unit of the charging technology should have a corresponding integrated DC fault current detection (DC fault protection). With professional installation of the wall box or the CEE socket, a simple type A residual current circuit breaker is sufficient in addition to the corresponding miniature circuit breaker.  Catalogue content:In this eibabo® catalogue Circuit breakers and fuses > Residual current circuit breaker (RCCB) you will find items from the following product groups:Item overview:Adapter plugCircuit breakerDifferential currentEarth leakage circuit breakerElectric charging stationHeat pump systemsIntermediate switchMain residual current circuit breakerPersonal protection machineRail mounted devicesRCCBResidual Current DeviceARCCBResidual Current DeviceBRCCBResidual Current DeviceFRCD switchResidual currentResidual current adapterSafety switchfrom the following manufacturers:Manufacturer overview catalogue Residual current circuit breaker:ABBBachmannBerkerDoepkeEatonGiraHagerJungSchneider ElectricSiemens
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
Combination rcd-line protection - What are the advantages of a residual current circuit breaker in combination with line protection? Where are these devices used? What specification should you look out for? Read this post to learn more. Electricity is an indispensable part of our life. But the fact is that electricity poses a risk to life and property. The main risks associated with electricity include electric shock and fire. Therefore, you should not be neglectful when protecting your circuits. The aim is to protect people from the risk of electric shock and fire. In the event of sudden ground faults, a residual current circuit breaker is particularly helpful. This ensures that in such cases the circuit is immediately interrupted. Circuit breakers are used in the event of overcurrents. With the combination of both devices you protect yourself against most dangers.Image: Hager ADZ316D residual current circuit breaker with line protectionWhat is combi FI line protection?Combination switches for residual current circuit breakers (FI) and line protection (LS) are also referred to as FI/LS combination switches. This FI/LS combination switch is a protective switching device that combines the functionalities of residual current circuit breakers and miniature circuit breakers. A residual current circuit breaker is an important safety measure when it comes to protecting electrical circuits. RCCB or RCD is also often mentioned. These are the abbreviations for the English terms 'Residual Current Circuit Breaker' and 'Residual Current Device'. It is a current sensing device that can automatically measure and disconnect the circuit. Disconnection occurs when a fault occurs in the connected circuit or the current exceeds the rated sensitivity of the device. Miniature circuit breakers are overcurrent protection devices when used in low-voltage networks. These are also called MCBs. MCB is the abbreviation for the English term 'Miniature Circuit Breaker'. Advantages:The combination FI line protection devices offer the following protection at the same time: short-circuit protection, overload protection, additional protection or error protection, protection against electric shock and preventive fire protection. While a residual current circuit breaker is only used to protect against earth faults and a miniature circuit breaker only to protect against overcurrent, the combination FI line protection protects against both types of faults.Where is combined RCD line protection required?The FI line protection combination devices we offer are used both in residential installations and in industrial applications. You can significantly increase the availability of a system with RCBOs. We recommend fitting a combi RCD to each individual circuit. Errors that occur in one circuit therefore do not impair the functionality of the other circuits. Assembly:The series installation devices are intended for installation in electrical distribution boards on the DIN rail. If you have electrical circuits that must remain functional at all times, a combi FI circuit breaker is the right choice. For example, think of the power supply for your aquarium, freezer or fire alarm. RCDs and miniature circuit breakers can still cause a power outage because they only detect one type of problem. In less important circuits, a residual current device or a simple miniature circuit breaker may be less expensive. However, consider their disadvantages when installing in critical systems.Can I replace a simple residual current circuit breaker with a combination FI circuit breaker?You can, of course, retrofit an FI/LS combination switch or replace your existing residual current circuit breaker with a combination FI circuit breaker. The prerequisite is that the cable sizes are appropriate considering the rating of the combined RCD. We recommend that the replacement be performed by a qualified electrician in accordance with the manufacturer's instructions and guidelines. He should check the resistance values and test the insulation. The isolation of the RCD combination switch should also perform within the appropriate specifications.What should I look out for when buying a combi RCD?When distinguishing between the individual RCBOs, please consider the tripping characteristics. Combination switches with B characteristics and C characteristics are available here. The key difference between Type B and Type C devices is their ability to tolerate surge currents without tripping. These are typically inrush currents in connection with reactive loads, which occur, for example, with lighting or motors (capacitive or inductive loads).Good to knowThe classification according to tripping characteristics is based on the nominal residual current at which instantaneous tripping occurs. This is usually less than 100 milliseconds. On the one hand, devices with high inrush currents should not trigger the RCBO combination switch unnecessarily. On the other hand, it should switch safely in the event of a short-circuit current.Type B devices are primarily suitable for domestic and light commercial applications. Here shift shocks are low or non-existent. Choose Type C equipment for commercial and industrial applications when you expect a certain level of electrical inrush current. In addition, there are devices of type D. These have only limited applications. Typically in industrial environments where high inrush currents are expected.Type B devices trip at fault currents that are three to five times the rated current. For example, a 10 amp device will trip at 30-50 amps.Devices with a C characteristic are designed in such a way that they trip at five to ten times the nominal current. A 10A device will respond at 50-100 amps. Choose a suitable model from a trusted manufacturer. The switching properties of cheap no-name devices can differ significantly from the specified values. Don't compromise on your own safety. In this catalog from the eibabo® shop you will find numerous residual current circuit breakers with line protection from leading manufacturers such as ABB, ABL, Busch Jaeger, Doepke, Eaton, Hager, Legrand Bticino, Schneider Electric and Siemens.Why does my combi RCD keep tripping?In addition to natural inrush currents, failure of connected equipment can trip a Type B combination switch in a residential or commercial environment. This is caused by high arc currents occurring at the time of failure. If unwanted trips persist, a Type-C device can replace a Type-B device, especially in commercial applications. Alternatively, it is possible to use a type B device with a higher power rating. Another reason can of course be a constantly present fault current in the installation or in the connected devices. Connected pluggable equipment should be removed in order to identify a defective device as the cause. If this is not the case, an electrician should be commissioned to check the electrical installation immediately. TIP:If a combination FI line protection trips, there is a reason. Increasing the tolerance threshold is only possible within certain limits. In this case, please look at your installation. The normal ratings for cables and wires refer to continuous operation under specified installation conditions. Of course, cables and wires can carry higher currents for a short time without being damaged. If the load becomes too high, please secure individual devices separately.  Catalogue content:In this eibabo® catalogue Circuit breakers and fuses > Earth leakage circuit breaker you will find items from the following product groups:Item overview:Circuit breakerCombination circuit breakerCombination switchEarth leakage circuit breakerLine protectionPersonal protection machineResidual currentfrom the following manufacturers:Manufacturer overview catalogue Combination rcd-line protection:ABBDoepkeEatonHagerSchneider ElectricSiemens

Circuit breaker accessory - A fire outbreak is one of the worst scenarios imaginable for a building. Within a few minutes, a fire can cause major property damage or destroy personal assets. So keep everything that is important to you. By installing a circuit breaker, you protect your lines from damage caused by excessive heating, which can occur as a result of overcurrent voltages. These automatic circuit breakers, also known as MCBs, are usually triggered by the thermal deformation of a bimetal and thus perform a similar function to circuit breakers, which are designed for switching load and short-circuit currents. Both devices switch off the circuit in the event of an overload. They have to be reset manually and can therefore be reused. To secure your installations, you can get high-quality and reliable miniature circuit breakers from well-known manufacturers at low prices in the eibabo online shop.Catalogue content:In this eibabo® catalogue Circuit breakers and fuses > Miniature circuit breaker (MCB) with auxiliary device you will find items from the following product groups:Item overview:AFDDArc fault detection deviceAutomaticBuilt-in deviceBuilt-in distributor deviceBuilt-in machineCircuit breakerCircuit breaker with additional deviceCircuit breaker with automatic restartCircuit breaker with integrated fire protection switching functionControl circuit breakerEB machineFire prevention circuit breaker by arc monitoring (MCB)Fire protection switchFire protection switch by arc monitoring (miniature circuit breaker)Fire protection switching deviceFire protection switching device AFDDGroup switchInstallation machineLS switchMCBMini circuit breakerMiniature circuit breaker (MCB)Miniature circuit breaker (MCB) with auxiliary deviceModular installation deviceOver current switchPlug-in circuit breakerScrew circuit breakerfrom the following manufacturers:Manufacturer overview catalogue Circuit breaker accessory:ABBEatonHagerSchneider Electric
Actuating drive - Do you want your heating systems to offer the desired living comfort while working efficiently? Then it should be equipped with durable and high-quality actuators that optimally control the flow of the heating medium. Find out more about actuators, their function and use here. Actuators are required to open and close the water circuit of a heating system or cooling ceiling. To do this, the drives are screwed or snapped onto a valve. Efficient heating of buildings has become a challenge. It is no longer just about warming the residents, but:adjust the temperature sensibly to the function of the roomusing as few resources as possibleto ensure a long service life of the systemto enable convenient operation All of these lead to money savings, environmental protection and a better quality of life, and depend in part on the heating system installed in the building. In this eibabo® catalog you will find conventional actuators for 24 volt systems or 230 volt systems. Depending on your needs, choose normally open or normally closed models and installation accessories.What are thermoelectric actuators?Thermoelectric actuators are general purpose actuators designed to provide on-off control of a variety of control valves. In private use, these are typically the valves of underfloor heating, but can also be used in industry for other heating systems, ventilation systems and cooling systems. The devices regulate the flow of the heating medium (e.g. hot water) in a circuit and thus ensure that the temperature in the building is controlled. Thermoelectric actuators can be used on the heater valves as well as in the heater manifolds and the floor manifolds.Please noteSome actuator models only suitable for certain valve inserts. Please read the product descriptions and pay particular attention to the dimensioning of the attachment on the valves and the type of power supply.Modern actuators work together with room thermostats and heating actuators and can be integrated into the building management system.Should I buy normally open or normally closed actuators?With actuators, we distinguish between NC (normally closed) and NO (normally open). Which variant you choose depends on your personal needs. NC drives are always closed and open when power is applied. In the case of normally open NO actuators, the current ensures that the valve closes. Please take this into account when planning your heating system. But what are the advantages or disadvantages? In the event of a power failure or defect, NC drives close. If it is a heating season, you will quickly notice the malfunction. It's getting cold in the house. NC drives therefore only consume electricity when they are being heated. On the other hand, drives that open without current are more efficient during the heating period. However, in the warm season you must keep the drives closed using electricity, otherwise you may heat your building unnecessarily. In such a case, switching off the pump by the heating actuator or manually after the winter season would be advisable.How are thermoelectric actuators installed?Thermoelectric actuators (valve drives) are snapped or screwed directly onto the upper part of the valve used in the house. This connection with the valve spindle is usually made directly in the heating circuit distributor. You can use adapters made of PVC or metal to compensate for the manufacturer-specific distance differences between the drive and the upper part of the valve or the thread and the mount. In this way you ensure correct implementation of the manipulated variable.Why are there no KNX actuators?With a decentralized installation, for example in the heating circuit distributor, you can use heating actuators with L and N connections for direct connection of the actuators. You can find more information in our 'Heating actuator' category. Contrary to widespread opinion, thermoelectric actuators are not wear-free and must be replaced every year. This is why earlier versions of expensive KNX actuators (i.e. devices that combine the KNX actuator and actuator) have not caught on and are increasingly disappearing from the market. It is therefore a question of long-term cost efficiency to separate the technology from the positioning drive and the actuator. The actuator is parameterized using the Engineering Tool Software ETS. TIPThe ETS parameter 'Flush' helps to minimize wear on rarely used valves. This function prevents the heating valves from calcifying too quickly. This KNX software is manufacturer-independent and is required to develop and configure individual controls for building automation. That means: The actuator opens and closes the actuators according to the programmed specifications.What should I look out for when buying an actuator?Reliable working actuators are the key to the correct and efficient operation of the entire heating system. When selecting thermoelectric actuators, you should pay attention to the following points:The drives must be compatible with the rest of the heating system. Check that these match the valves. An important parameter here is the so-called stroke, which is usually specified in millimeters. The stroke of the actuator must match the closing dimension of the valve. If the stroke is too small, the actuator will not fully open or close the valve (depending on the NO or NC variant).Decide on a normally open or normally closed variant.Pay attention to the power supply. Here we distinguish between 24 volts and 230 volts.The power consumption of the drive should be as low as possible and not exceed 5 watts.Opening and closing a valve takes time. High-quality equipment offers opening and closing times of less than 3 minutes.The actuator should have an easily recognizable status display so that the current status can be easily read. Image: ABB TSA/K 230.2 thermoelectric actuatorIn addition to thermoelectric actuators, we offer you the following products:radiator valve drivesActuators including binary inputselectromotive actuatorsRadiator control drivesWireless actuators with and without room temperature controllerRadiator thermostatsstraight valvesvalve adapterReceiver for heating actuatorsand many more Well-known brand manufacturers in our range include ABB, Busch-Jäger, Eaton, Gira, Hager, Heimeier, Issendorf, Lingg & Janke, Merten, MDT, Siemens, Somfy and Theben.  Catalogue content:In this eibabo® catalogue Installation bus systems > Actuating drive for bus system you will find items from the following product groups:Item overview:ActuatorBattery poweredBus technologyContinuous controlControl valveEnergy efficientHeater driveHeating controlHeating controllerHeating technologyRadiator thermostatRetrofitRoom temperature controllerRoom thermostatTemperature controlTemperature controllerThermostatTime profileValve driveWax cartridge drivefrom the following manufacturers:Manufacturer overview catalogue Actuating drive:ABBAVM ComputersystemeBusch JaegerEberleEltakoFKRGiraHagerIssendorffJungMertenRademacherSiemensSomfyThebenWindowMaster
