Abstract

1435544 Automatic circuit-breakers WESTINGHOUSE ELECTRIC CORP 30 July 1973 [31 July 1972] 36226/73 Heading H1N A disposable circuit-breaker has an operating mechanism releasably restrained by an armature member 63 responsive to movement of a bimetallic element 59 which deflects in response to sustained overcurrents of a first value, electromagnetic tripping means provided by a magnetic member 85 on the element 59 which attracts the armature 63 in response to fault currents of a second value higher than the first, a fusible link 91 in series in the normal current path through the circuit-breaker and fusing in response to current exceeding a threshold above the second value, and a housing enclosing these components and formed by members secured together by rivets 11, or other means, which have to be destroyed before the housing members can be separated. Thus a short-circuit current which might damage the bimetallic element, blows the link which cannot be easily replaced.
