Abstract
A circuit breaker includes separable contacts, a trip mechanism having an armature mechanism responsive to selected conditions of current flowing through the contacts, and an operating mechanism for opening and closing the contacts. The operating mechanism includes an open position, a closed position, a tripped open position, a lock, a first link and a second link having a base and a pair of legs. The lock is pivotally mounted to and substantially between the legs of the second link. The first link is pivotally mounted to the second link. The first link and the second link have an unbroken state in the closed position and a broken state in the tripped open position. The lock maintains the unbroken state in the closed position and responds to the armature mechanism to release the first link and the second link to the broken state in the tripped open position.
