Abstract:
    A circuit breaker suppresses generation of an arc and enhances breaking performance by simplifying structure and evidently reducing part number. A first fixed conductor is installed on a power source side, a second fixed conductor is installed on a load side, and an intermediate conductor is installed between the two fixed conductors. A first and a second movable conductors are positioned between a power source side fixed conductor and a load side fixed conductor to interpose an intermediate fixed conductor to constitute a series electric circuit with each conductor, wherein the ON/OFF devices basically at the same time open the movable conductors between the power source side fixed conductor and the intermediate fixed conductor and between the load side fixed conductor and the intermediate fixed conductor.
