ABSTRACT:
The generator circuit breaker includes synchronization means for separating its main contacts before its arcing contacts are separated. It has a lever which is hinged at one of its ends to a fixed contact piece and which is constrained to move firstly with the moving main contact and secondly with the moving arcing contact by means of a spring, and with a ramp having two horizontal levels interconnected by a sloping intermediate portion, the ramp serving as a sliding support for a trigger member which prevents or authorizes movement of the moving arcing contact. This organization makes it possible for the moving contacts to be synchronized mechanically in simple and single manner.
