Abstract
A trip bar is provided for an electrical switching apparatus, such as a circuit breaker. The circuit breaker includes a housing, an operating mechanism, and a number of accessories installable within the housing. At least one of the accessories has an actuator, such as a stem. The trip bar includes an elongated pivot member having a first end pivotably coupled to the operating mechanism, a second end disposed opposite and distal from the first end, and at least one protrusion extending outwardly from the elongated pivot member between the first and second ends. Such protrusion is actuatable by the stem to pivot the elongated pivot member. A deflecting mechanism, such as a cam surface, is disposed at or about the second end of the elongated pivot member. When such one of the accessories is being installed within the housing, the stem deflects the cam surface to facilitate insertion.
