Circuit interrupter including a molded case made of liquid crystal polymer

摘要

A circuit interrupter includes a housing having a molded case made of liquid crystal polymer. Separable contacts are disposed within the housing. An operating mechanism is disposed within the housing and is structured to open and close the separable contacts. A trip mechanism is disposed within the housing and is structured to cooperate with the operating mechanism to trip open the separable contacts. The trip mechanism includes an electronic trip circuit and a rigid, conductive base providing a ground to the electronic trip circuit. The rigid, conductive base is insert molded to a portion of the molded case.
