Abstract
A circuit breaker includes a case, separable contacts having a fixed contact and a movable contact, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a closed position, an open position, an operating handle for moving the operating mechanism between the open and closed positions, a movable contact arm carrying the movable contact, a linkage having a first end and a second end, and a snap lever. The second end of the linkage is pivotally mounted to the movable contact arm. The snap lever holds the linkage in the open position of the operating mechanism and releases the linkage as the operating handle moves from the open position toward the closed position of the operating mechanism, in order to snap close the separable contacts.
