Description of the Related Art An electromagnetic current breaker of the type described at the beginning, as shown in FIG. 2, is a conventional protective switch which protects a single-pole or multi-pole electrical load from an unacceptable operating state. It has been used to detect current, especially short-circuit current. The protection switches are a power circuit breaker, a motor protection circuit breaker, and a wiring protection circuit breaker. These circuit breakers must interrupt the overcurrent within a predetermined response time according to electrical standards. For this purpose, the current interrupter opens the contact to be opened of the protective switch in response to overcurrent or short-circuit current,
In some cases, it is linked so as to remain open.
