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.

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

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
