ABSTRACT:
A circuit breaker which is remote controllable by an external remote control switch by way of an electronic control unit and an electromagnetic switch drive controlled by the electronic control unit. The switch drive switches the electric circuit by a switch lock, which is latched to it and which, during an overload, is unlatched and opened by way of the release of the bimetal of switch drive and, as a result, interrupts the electric circuit. During bimetal release, an auxiliary switch is actuated, which by way of the electronic control unit turns the remote control switch off and re-latches switch drive with the opened switch lock.
