An mcb or miniature circuit breaker is an electromagnetic device that embodies complete enclosure in a molded insulating material. The main function of an mcb is to switch the circuit ie to open the circuit which has been connected to it automatically when the current passing through it mcb exceeds the value for which it is set.
