ABSTRACT:
In a movable contactor device in a circuit breaker, two contactor elements are arranged in such a manner that they are in parallel with each other and are independent of each other, to form a movable contactor for each phase. The two contactor elements have respective movable contacts separated from each other, and are rotatably coupled through a supporting shaft to a connecting conductor having three prong-shaped contact pieces. The number of contact points with the stationary contact can be increased as much.
