    摘要： A push-to-trip assembly is provided for an electrical switching apparatus, such as a circuit breaker. The push-to-trip assembly includes a push-to-trip actuator having first and second ends and being movable among a first position corresponding to the circuit breaker separable contacts being closeable, and a second position corresponding to the second end cooperating with a trip bar to cause the circuit breaker operating mechanism to trip open the separable contacts. The first end is accessible from the exterior of the housing to actuate the push-to-trip actuator from the first position to the second position. A biasing element biases the push-to-trip actuator away from the base toward the first position. At least one cover stop of the push-to-trip actuator engages a corresponding portion of the housing cover to stop movement of the push-to-trip actuator. An overtravel restraint proximate the second end of the push-to-trip actuator restrains movement of the trip bar.

    摘要： A chimney is provided for a circuit breaker arc hood assembly. The circuit breaker housing includes a number of arc chute vents (20) structured to exhaust arc gases. The arc hood assembly includes a body having a first side facing the housing, and a second side opposite the first side. The first side includes a number of apertures. The chimney includes a base disposed at or about a corresponding one of the arc chute vents, a duct (204) extending outwardly from the base and through a corresponding one of the apertures, and a plurality of resilient protrusions (206,208) movably coupling the chimney to the first side of the body at or about the corresponding one of the apertures. The resilient protrusions bias the base toward engagement with the housing to resist the arc gases being undesirably discharged between the base and the housing.

    摘要： An accessory tray is provided for an electrical switching apparatus, such as a circuit breaker, including a housing, an operating mechanism, and a number of accessories. The housing has a cavity with a first end and the second end, and is disposed beneath the operating mechanism. The accessory tray includes an elongated member including first and second ends and is structured to receive the circuit breaker accessories. A guide mechanism guides the elongated member into and out of the cavity, in order to install the circuit breaker accessories beneath the operating mechanism. When the elongated member is disposed within the cavity, the first end is disposed at or about the cavity first end and the second end is disposed at or about the cavity second end. The accessory tray may be a single-piece molded member having a plurality of mounting portions for removably securing a plurality of circuit breaker accessories.
