ABSTRACT:
A molded case circuit breaker employs a multiple latch assembly for maintaining the circuit breaker operating mechanism in a closed condition. The multiple latch assembly includes three separate latch levers mounted on a common latch support frame. The multiple latch arrangement substantially reduces the amount of tripping force required to articulate the circuit breaker operating mechanism.
