ABSTRACT:
A circuit breaker includes a housing having a first insulating portion, a line end, a load end and a pair of separable contacts electrically disposed between the line end and the load end. An operating mechanism includes a second insulating portion and a movable arm carrying one of the separable contacts. The operating mechanism is structured to move the separable contacts between an open position and a closed position. A shunt is electrically interconnected between the movable arm and one of the line and load ends. The first insulating portion is disposed between the separable contacts and a portion of the shunt. The first and second insulating portions cooperate at or about the closed position of the separable contacts to prevent an arc from passing from the separable contacts to the conductor.
