ABSTRACT:
A circuit breaker wherein one or two of circuit-breaking electric element blocks respectively including current source side and load side terminals, fixed and movable contactors, means for forcibly tripping the movable contactor away from the fixed contactor by operating at least electromagnetically responsive to an overcurrent and an arc suppressing means, and movably supporting the movable contactor at a stationary part of the tripping means is arranged in each of side spaces within a single housing, while a single mechanical contact operating mechanism for moving the movable contactor in each of the blocks between both positions of opening and closing contacts responsive to an external operating force and operatively connected with the tripping means of the blocks is contained in an intermediate space provided between the side spaces, in each of the latter of which the movable contactor of an elongated member is arranged with one end having the movable contact directed toward the source side terminal and with the other supported end directed toward the load side terminal, the arc suppressing means is arranged on the side of the source side terminal and the tripping means is arranged on the side of the load side terminal remote farthest from the arc suppressing means.
