Patent ID: 7012795

Claim:
A circuit breaker assembly comprising; first and second electromagnetic circuit breakers, each having linkages including electromagnetic coils and armatures, a common trip link coupling said linkages to trip both linkages in response to movement of either armature in response to energizing of either coil, said circuit breakers having terminals electrically connected to said coils respectively, a reverse polarity circuit coupled between said circuit breaker terminals, said reverse polarity circuit when conductive serving to reduce the voltage presented to the terminals of said first circuit breaker while such voltage is reversed, said second breaker having its terminals connected in electrical parallel with said first circuit breaker terminals during a reverse polarity condition, and said first circuit breaker having contacts that open to interrupt current through its coil, and said second circuit breaker being electrically uninterruptible so that said reverse polarity circuit remains conductive at said reduced voltage to protect the breaker assembly and any load circuit associated therewith when resetting said breaker assembly under continuing reverse polarity conditions.
