Electrical switching apparatus and shaft assembly therefor

摘要

A shaft assembly (100) is provided for an electrical switching apparatus (2), such as a circuit breaker. The circuit breaker includes a housing (4) and a pivotal shaft (10). The shaft assembly (100) includes a paddle assembly (102) comprising an elongated body (104) including a first end (106) and a second end (108) disposed opposite and distal from the first end (106). A number of paddles (110,112) extend radially outwardly from the elongated body (104). A support bracket (114) is coupled to the housing (4) of the circuit breaker. The first end (106) of the elongated body (104) is coupled to and supported by the pivotal shaft (10) , and the second end (108) of the elongated body (104) is coupled to and supported by the support bracket (114). The support bracket (114) is preferably an accessory mounting bracket. The paddle assembly (102) preferably further includes a separate molded member (130). When the separate molded member (130) moves, the elongated body (104) moves. However, the elongated body (104) is pivotable independently from the separate molded member (130).
