The miniature switch (MCB) is an electromechanical device for protection of circuits that operate automatically. The MCB is used to cut off a circuit that is overloaded and shorted. MCBs are a good alternative to fuses. Among the important advantages of i-switch miniature switches: Switching: Miniature switches can be turned on and off manually. This function is very useful during the maintenance of electrical installations. Overcurrent protection: When a part of the equipment is overloaded (more current than meKills), the bimetal heats up and bends, releasing the toggle. As a result, the connections open and the equipment fails. Short circuit protection: During a short circuit, a sudden increase in current produces a powerful driving force to release the toggle, and the connections are released. Load, spark is created between fixed and movable connections. The connections are designed in such a way that the spark formed goes towards the spark plug. The task of the igniter is to reduce the length of the spark, break it and turn it off.
