    摘要： A moveable contact arm assembly (18) includes a moveable contact arm (20) having a moveable contact (22) thereon. Also included is a carrier assembly (32) operatively coupled to the moveable contact arm. Further included is a first end plate (42) operatively coupled to the carrier assembly and a bottom bracket (50) operatively coupled to the first end plate. Yet further included is a first latch member (84) coupled to the bottom bracket, the first latch member comprising a first guiding surface and defining a first recess portion (94). Also included is a guide pin (116) extending from the carrier assembly and in contact with the first guiding surface of the first latch member during movement of the moveable contact arm assembly. Also included is a first stop pin (120) extending from the carrier assembly and disposed in the first recess portion of the first latch member in the blow open condition of the circuit breaker.

    摘要： A contact system of a circuit breaker includes a fixed contact. The contact system also includes a moveable contact arm assembly comprising at least one moveable contact arm having a moveable contact thereon, the moveable contact arm moveable to define a closed condition and a blow open condition. The contact system further includes a carrier assembly operatively coupled to the moveable contact arm. The contact system yet further includes a latch plate operatively coupled to the carrier assembly. The contact system also includes a trip shaft operatively coupled to the carrier assembly, the trip shaft having a non-circular region defining an engagement surface disposed in contact with the latch plate in the closed condition. The contact system further includes a biasing portion of the moveable contact arm configured to rotate the trip shaft out of engagement with the latch plate and into the blow open condition.
