Abstract:
A pole shaft catch assembly is for an electrical switching apparatus, such as a circuit breaker. The circuit breaker includes a housing, separable contacts enclosed by the housing, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a pole shaft pivotably coupled to the housing and a yoke assembly coupled to the pole shaft. The pole shaft catch assembly includes a catch arm. The catch arm moves between an engaged position in which the catch arm engages the yoke assembly to restrict movement of the yoke assembly and the pole shaft, and a disengaged position in which the catch arm disengages the yoke assembly. A biasing element biases the catch arm toward the disengaged position. A trigger translates movement of the yoke assembly into movement of the catch arm.
