Abstract
A power circuit breaker is disclosed wherein an electric current is monitored by an electronic trip unit in order to detect an electrical fault. In an embodiment, a first magnetic device of the power circuit breaker, in the event of a fault being detected, is configured to be excited which, when it is excited, trips a trip mechanism via a plunger. As a result of tripping, the trip mechanism disconnects two contacts via which the current flows. The power circuit breaker of an embodiment includes a second magnetic device which is likewise able to be excited by the ETU and by which the trip mechanism is likewise able to be tripped.
