摘要： A circuit interrupter which comprises a pair of separable contact structures each including a contact element, at least one of the contact structures being movable between a closed position and an open position relative to the other contact structure for opening and closing an electric circuit extending through the circuit interrupter, the movable contact structure having an arm support that is pivotable about an axis, a movable contact arm pivotally supported on the arm support and extending in a parallel and an opposite direction to the other contact structure for generating an electromagnetic repulsive force therebetween, and a biasing means connected between the arm support and the movable contact arm for biasing the movable contact arm to a predetermined position with respect to said arm support, and an operating mechanism connected to the arm support of the movable contact structure for separating the movable contact structure from the stationary contact structure in response to an overcurrent flowing through the circuit interrupter, the movable contact arm having a common pivot axis to the pivot axis of the arm support.

摘要： A circuit interrupter comprises a housing including a housing wall, an interrupting mechanism including a pair of separable contacts and an operating mechanism, and an optional accessory unit used in connection with an opening operation of the interrupting mechanism. The optional accessory unit may be a unit which includes a movable member operable in connection with the opening operation of the interrupting mechanism, such as an alarm switch, an auxiliary switch, a voltage trip device or an under voltage trip device. The optional accessory unit may be a connecting terminal block connectable between an external circuit and the circuit interrupter. The housing has formed in the outer surface thereof a receptacle cavity for receiving therein the optional accessory unit. When the unit is received in the cavity, no substantial portion of the unit projects from the housing. A fastening means comprises a slider, a guide rail engaging the slider for allowing a sliding movement of the optional accessory unit only in the direction of extension of the guide rail, and a screw for securing the optional accessory unit to the housing wall.
