To also break a power supply side terminal from a power supply even in which a connection failure occurs in a power supply side terminal.SOLUTION: A circuit breaker comprises: overcurrent detection means of detecting an overcurrent of a cable way L; a breaking part 6 that breaks the cable way L; a connection failure detection part 4 that detects a connection failure even in the case where the connection failure occurs in any one of a power supply side terminal 2 and a load side terminal 3; and a control part 8 that makes the breaking part 6 break and operate even if the connection failure occurs, and includes a signal input and output part 7 that is communicated with an external part via a signal wire M. The control part 8 outputs a predetermined signal from the signal input and output part 7 to a specific transmission destination if the connection failure detection part 4 detects the connection failure, and makes brake and operate the breaking part 6 if predetermined signal addressed to itself is transmitted to the signal input and output part 7.SELECTED DRAWING: Figure 1 【課題】 電源側端子で接続不良が発生した場合は、電源側端子も電源から遮断する。【解決手段】 電路Ｌの過電流を検知する過電流検知手段と、電路Ｌを遮断する遮断部６と、電源側端子２及び負荷側端子３の何れかの端子に接続不良が発生したらそれを検出する接続不良検出部４と、接続不良が発生したら遮断部６を遮断動作させる制御部８とを備え、信号線Ｍを介して外部と通信する信号入出力部７とを有し、制御部８は接続不良検出部４が接続不良を検出したら、信号入出力部７から特定の送信先に所定の信号を出力させると共に、信号入出力部７に自身宛の所定の信号が送信されたら、遮断部６を遮断動作させる。【選択図】 図１
