Abstract:
A thermal trip assembly is for an electrical switching apparatus. 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 thermal trip assembly includes a load conductor, a bimetal adapted to cooperate with the operating mechanism to open the separable contacts in response to a trip condition, and a bypass heater element structured to be electrically connected to the shunts. The bypass heater element directs the flow of electric current to at least partially bypass the bimetal.
