Abstract
An electrical switching apparatus such as, for example, a subminiature or aircraft circuit breaker, is provided for a circuit protection module of an electrical system, such as an aerospace power distribution unit. The circuit protection module includes a panel member. 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 mounting element for attaching the housing to the panel member. The housing is a thermally conductive liquid crystalline polymer. The panel member and mounting element are thermally conductive. Heat generated by the separable contacts is transferred away from the separable contacts, through the housing and the thermally conductive mounting element, and into the thermally conductive panel member. A circuit protection module and an electrical system are also disclosed.
