Abstract
In order to reduce the breaking energy of a high-voltage or medium-voltage circuit-breaker, the interrupting chamber () contains two contacts () mounted to move in opposite directions, actuated via a single device (). The two contacts () are driven in opposite directions by a cylindrical cam () having slots () that co-operate with fixed rods (), each of which is connected to a respective one of the contacts (): the profiles of the slots () make it possible to manage the speed and the amplitude of the movement of the second contact () relative to the main contact () without requiring any complex design.
