Abstract
A circuit breaker includes a housing having first and second openings, with stationary and movable separable contacts disposed therein. An operating mechanism is disposed in the housing, is coupled to the separable contacts and is structured to move those contacts between open and closed positions. A trip mechanism is disposed in the housing and cooperates with the operating mechanism to trip open the separable contacts. A slot motor assembly is disposed about the separable contacts and has upper and lower slot motor portions. The upper slot motor portion is disposed above the movable contact and the lower slot motor portion is disposed below the stationary contact. The upper slot motor portion includes a rigid, laminated steel member having a general U-shape, with a bight portion, and first and second legs. The first and second legs engage the housing at the respective first and second openings.
