ABSTRACT:
Certain exemplary embodiments comprise 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; and 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, said integral electronic trip device comprising a solenoid adapted to actuate upon at least one of said ground fault and said arc fault, said solenoid comprising a plunger, said plunger comprising a plunger tip located at an end of said plunger and defined about a longitudinal axis of said solenoid, said plunger tip adapted to contact and move a biased armature.
