Abstract:
A circuit breaker comprising:a housing;separable contacts mounted in said housing;an operating mechanism for opening said separable contacts when actuated;trip means for actuating said operating mechanism in response to predetermined current conditions and including electronic trip means incorporating a first test circuit, a first test switch including a first switch contact, a second test circuit with a second test switch including a second switch contact, and a common contact, said first switch contact and said second switch contact comprising cantilevered electrically conductive springs selectively deflectable in generally orthogonal planes into engagement with said common contact; anda common actuator moveable to a first position to deflect only said first switch contact into engagement with said common contact to actuate only said first test switch, and moveable to a second position to deflect only said second switch contact into engagement with said common contact to actuate only said second test switch, and a neutral position in which neither test switch is actuated.
