A circuit interrupter comprises a contact arm assembly for supporting the movable contact composed of a first contact arm and a second contact arm pivotally supported by a common pin, the first contact arm having an elongated guide hole extending in the direction of movement of the movable contact, the second contact arm having an elongated hole extending substantially in the direction of extension of the second contact arm. A second pin extends through the elongated hole and the guide hole, and a spring is provided for biasing the second pin. The elongated hole has a pin sliding surface on which the second pin slides and which forms an angle of 90.degree. or more with respect to a pin sliding surface of the elongated pin guide hole when the first contact arm is being reset after the second contact arm is separated by an electromagnetic repulsive force.
