Bimetallic Circuit Breaker With An Auxiliary Switch
US Patent:
4518943, May 21, 1985
Filed:
May 7, 1984
Appl. No.:
6/607428
Inventors:
George J. Giessner - Cherry Hill NJ
Assignee:
Heinemann Electric Company - Lawrenceville NJ
International Classification:
H01H 7116
US Classification:
337 68
Abstract:
A bimetallic circuit breaker with a first or main set of movable and stationary contacts. The circuit breaker includes an electrical insulating slide restrained in one position by the movable contact and interposed between the contacts when these contacts are in the open position. The slide is carried by an insulator frame received within a housing of electrical insulating material. The frame is provided with a second or auxiliary set of movable and stationary contacts. The slide is positioned relative to the auxiliary contacts so that it keeps the auxiliary movable contact separated from the corresponding stationary auxiliary contact. When the bimetal flexes sufficiently, the slide is released and the main contacts open, and at such times the slide moves away from the auxiliary movable contact, permitting the auxiliary contacts to close for signalling, at a remote location, the opening of the main contacts. The circuit breaker includes a case having an end wall. The main set of contacts are carried by a pair of main terminals which extend through the end wall.
