ABSTRACT:
A circuit breaker includes a molded housing and separable contacts for movement between a closed position and an open position. An operating mechanism moves the separable contacts between their closed and open positions. A trip mechanism includes a trip bar which rotates to trip the operating mechanism from a first position to a second position corresponding to the open position of the separable contacts. A mechanical mechanism includes an interlock cam which selectively prevents the trip bar from rotating to trip the operating mechanism.
