Abstract
A composite circuit breaker comprises a closing switch part disposed between a pair of conductors at a position relatively near a load apparatus, a vacuum circuit-breaking part disposed between the conductors at a position adjacent to the closing switch part but relatively remote from the load apparatus, an operating mechanism operating the making and breaking operation of the closing switch part and vacuum circuit-breaking part, and a delaying mechanism including a delaying lever for delaying the making and breaking operation of the vacuum circuit-breaking part actuated by the operating mechanism relative to that of the closing switch part operated by the operating mechanism.
