摘要

A pole shaft assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, separable contacts enclosed by the housing, and an operating mechanism structured to open and close the separable contacts. The pole shaft assembly includes a shaft structured to cooperate with the operating mechanism and to be pivotably coupled to the housing. A number of throw assemblies are disposed on the shaft, and are secured with respect to the shaft with fasteners. The shaft includes first and second opposing ends and an elongated body portion extending therebetween. The elongated body portion of the shaft has a cross-sectional shape comprising a number of orienting features.
