ABSTRACT:
A shunt separator is provided for an electrical switching apparatus including a housing, separable contacts enclosed within the housing, an operating assembly including a trip bar, and a trip assembly. The trip assembly cooperates with the trip bar to trip open the separable contacts in response to a fault condition. The trip assembly includes a number of shunts. The shunt separator includes a molded projection, which extends outwardly from the housing of the electrical switching apparatus. The molded projection at least partially surrounds a portion of the trip bar, thereby separating the number of shunts from the trip bar.
