摘要： A spout for a connection between a bus bar and a circuit breaker in switchgear includes a housing and a fixed contact. The housing is formed of insulative material and includes a tubular body having an inner cavity and a radial first ventilation opening, a base portion having a first longitudinal opening, and a fixed contact receiving portion having a second longitudinal opening. The fixed contact is formed of a conductive material, has an outer contact surface exposed through the second longitudinal opening, and forms a portion of an outer surface of the spout. A switchgear includes a wall dividing a circuit breaker compartment from a bus bar compartment, and the base portion of the spout is securable to the wall. A method of increasing heat dissipation within switchgear using the spout includes securing a bus bar to the outer contact surface, and dissipating heat through the radial ventilation opening.

摘要： An electrical switching apparatus including a housing, a circuit interrupter mechanism movably disposed in the housing, and a damper assembly. The damper assembly includes a bracket that secures the damper assembly to the housing. A damper body is adjustably secured to the bracket. A stopper is coupled to the damper body and arranged to limit relative movement of the circuit interrupter mechanism with respect to the damper assembly. A damper rod extends through an opening in the stopper and has a surface that is arranged to interact with the circuit interrupter mechanism. The damper rod is arranged to damp movement of the circuit interrupter mechanism with respect to the damper body when the circuit interrupter mechanism is in contact with the surface of the damper rod.
