Generally, most commercial kitchens, elevators, and offices have this shunt trip breaker because it is required. Mostly, installing a shunt trip relay requires that the breaker and the shunt be from the same maker.
Also, not all breaker models are compatible with this accessory. Note: Every circuit breaker comes with different instructions. It would depend on the brand and model of the breaker. However, the critical part of every installation is that you need to connect the shunt to your sensor.
You may need a shunt trip breaker diagram as a reference to ensure correct installation. Also, check the brand and model of your breaker before proceeding with the installation. Some makers only allow a factory install of the shunt trip and other accessories. DIY installation may void the warranty of your breakers. Shunt trip breakers are important safety features in preventing damage to electrical equipment as well as injury to people. Overall, shunt trip breakers add additional safety features to breakers and ultimately play an important role in the electrical system.
They shut off electrical power during emergencies and serve to prevent damage to equipment and injury to people. Why are Shunt Trip Breakers Important? Next Post ». If this is not done, after a while the machine will shut down again. It is important that the AB rating corresponds to the cable cross-section. If it is less than necessary, then the operation will occur even under normal load, and if it is more, then the thermal release will not react to a dangerous excess current, and as a result, the wiring will burn out.
In order to protect electric motors from prolonged overloads and phase loss, thermal trip relays can also be installed on these units. They are several bimetallic plates, each of which is responsible for a separate phase of the power unit. Having figured out how an automatic machine with a thermal release works, let's move on to the next question.
The protective device, the analysis of which we have just carried out, does not work immediately it takes at least a second , therefore it is not able to effectively protect the circuit from short-circuit overcurrents.
To solve this problem, an electromagnetic release is additionally installed in AB. The releases of electromagnetic type circuit breakers include an inductor solenoid and a core. When the circuit is operating normally, the flow of electrons passing through the solenoid forms a weak magnetic field that is unable to influence the function of the network.
When a short circuit occurs, an instantaneous increase in the current strength occurs tens of times, and the power of the magnetic field increases in proportion to it. Under its influence, the ferromagnetic core instantly shifts to the side, affecting the shutdown mechanism.
Since the process of strengthening the magnetic field during a short circuit occurs in a fraction of a second, the electromagnetic release under its influence is triggered instantly, turning off the mains power.
This avoids serious consequences associated with short-circuit overcurrents. In case of line to line service, you can put the switch leg to any of the lines. Darren 29 April at Dwayne Dwayne 1 June at Matthew Carter 9 September at Unknown 9 October at Subscribe to: Post Comments Atom.
