Abstract
A shunt tab assembly is for an electrical switching apparatus, such as a circuit breaker. The electrical switching apparatus includes a housing, separable contacts enclosed by the housing, an operating mechanism for opening and closing the separable contacts, and a number of shunts. The operating mechanism includes a trip unit. The shunt tab assembly includes a shunt tab structured to be electrically connected to the shunts, a biasing element structured to bias the shunt tab toward a predetermined position with respect to the housing, and a fastener structured to mechanically couple and electrically connect the trip unit to the shunt tab.
