Abstract

An electrical circuit breaker device comprising an interrupting arrangement that completes an electrical circuit when the circuit breaker is in a closed condition and that interrupts the circuit when the circuit breaker trips, the interrupting arrangement having an actuating member which is retained by a latch movably mounted when the circuit breaker is in the closed condition and which is released by the latching member to actuate the interrupting arrangement to an open condition when the circuit breaker trips, characterized in that trip means comprising an electromagnet are provided (19) through which current controlled by the circuit breaker passes, the electromagnet being arranged to act on an armature (27) that is movably mounted to apply at least some of its movement to the coupling member (17), in order to move the hitch member with it to trip the circuit breaker, when a co current in excess of a given threshold current.
