ABSTRACT:
A reset lever is actuated in response to circuit breaker movable contacts swinging from their closed position to their tripped open position to exert a resilient force effective in reseating the plunger of a flux shifting-type trip solenoid. The reset lever also actuates a trip lever into tripping engagement with a circuit breaker trip latch assembly in the event the movable contacts are blown open by a high level fault current.
