Patent ID: 7091438

Claim:
A circuit breaker comprising: a first conductor comprising an elongated portion; a second conductor comprising a movable arm; a set of contacts comprising at least a first stationary contact and at least a first movable contact, the at least a first movable contact and the at least a first stationary contact being separable to interrupt a circuit that includes the first and second conductors; the at least a first stationary contact being disposed on the first conductor; the at least a first movable contact being disposed on the movable arm; an arc extinction system comprising at least a first insulator disposed adjacent the at least a first stationary contact, the at least a first insulator being structured to output a gas upon an initiation of an arc between the at least a first stationary contact and the at least a first movable contact to resist movement of the arc in a direction generally toward the at least a first insulator; and the elongated portion extending adjacent at least a portion of the movable arm to form a reverse loop with the at least a portion of the movable arm, at least a portion of the at least a first insulator being disposed between at least a portion of the elongated portion of the first conductor and the at least a portion of the movable arm.
