    • PROBLEM TO BE SOLVED: To enable a movable contactor to be open-electrode driven at a high speed by devising arrangement of a fixed contact and the movable contact, when overcurrent flows, while aiming at making the size compact for a current shielding part by using linear contactor conductors as fixed contactors of a power-supply side and a loaded side.
      SOLUTION: In a circuit breaker for wiring, in which the current interruption part is constituted by combining an insulating case 6, fixed contactors 7A, 7B of the power-supply side and the loaded side arranged and diagonally arranged inside the case, a rotating movable contactor 8 of a bridge type, a contactor body 9, and arc-extinguishing devices 10, a height H is reduced by using the linear contactor conductors as the fixed contactors of the power-supply side and the loaded side, a Z-shaped electrifying path is formed between the fixed contactors of the power-supply side, as well as the loaded side and the movable contactor, by arranging respective fixed contactors to mutually face in vertically parallel, and the movable contactor is made to be open-electrode driven by an electromagnetic repulse force, when the overcurrent flows.

    • PROBLEM TO BE SOLVED: To provide a breaker for multipole wiring which realizes the balance of contact pressure of a contactor in a monopole breaking unit relatively far from an opening and closing mechanism and reliability of opening and closing operation of the contactor.
      SOLUTION: The breaker for multipole wiring comprises a substrate positioned between a monopole breaking unit relatively far from the opening and closing mechanism comparing with other monopole breaking unit and its neighboring monopole breaking unit among the plurality of monopole breaking units; a link mechanism rotatably supported on the substrate and providing compensation rotaion moment to a driving shaft not to make the contact pressure between the contactors in the monopole breaking unit relatively far from the opening and closing mechanism lower than the contact pressure between the contactors in other monopole breaking unit; and a spring having one end part supported by the substrate and the other end part supported by the link mechanism to provide elastic force to apply the compensation rotation moment to the link mechanism.
