Abstract:
1. An apparatus, comprising: a circuit breaker comprising: an integral thermo-magnetic trip device adapted to trip said circuit breaker upon an occurrence of a current overload and adapted to trip said circuit breaker upon an occurrence of a voltage spike of at least a predetermined level; an integral electronic trip device adapted to trip said circuit breaker upon detection of a ground fault and adapted to trip said circuit breaker upon detection of an arc fault; and an armature adapted to cause a trip of said circuit breaker upon a predetermined movement of said armature, said armature comprising a contact zone adapted to be moved by a substantially cylindrical plunger that defines a longitudinal axis of a solenoid, said solenoid adapted to project said plunger along said longitudinal axis, said longitudinal axis intersecting said contact zone.
