摘要:
A circuit breaker includes a housing having an opening, separable contacts within the housing, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a generally transparent operating handle having a portion protruding through the opening of the housing. An auxiliary switch associated with the operating mechanism provides a first normally closed output when the separable contacts are open and a second normally open output when the separable contacts are closed. A first LED indicator cooperates with the first output, is proximate the operating handle and is illuminated when the separable contacts are open. A second LED indicator cooperates with the second output, is proximate the operating handle and is illuminated when the separable contacts are closed. One of the first and second LED indicators illuminates the operating handle.
