Summary:PROBLEM TO BE SOLVED: To provide a remote-control circuit breaker capable of suppressing the generation of an arc caused by the switching of a relay contact. SOLUTION: The circuit breaker is provided with a coupling piece 67 extended toward the opposite side of a main fixed contactor 80 through the side of a main movable contactor 81 so as to cross from the other end side of the main fixed contactor 80 to the other end side of the main movable contactor 81, an arc driving piece 68 extended from the coupling piece 67 nearly in parallel toward one end side of the main movable contactor 81 in a way opposing the main movable contactor 81, and an arc driving body 66 with the other end of a relay fixed contactor 90 connected to one end of the arc driving piece 68. A case 2 of a body 1 has a support part 61 arranged between a main fixed contact 80a and a relay fixed contact 90a and rockingly supporting the arc driving body 66 due to the placement of the main fixed contactor 80 to the case, whereby, the relay fixed contact 90a turns in a direction toward the relay movable contact 91a with the support part 61 as a fulcrum when the main contacts are closed.
