GROUND-FAULT CIRCUIT BREAKER

PROBLEM TO BE SOLVED: To provide a ground-fault circuit breaker which is downsized while securing a suction force of a ground-fault removal device for removing a trip bar.SOLUTION: A ground-fault circuit breaker comprises: a base 11; power source side terminals 20 which are arrayed while being spaced on the base 11 and connected to a cable run; a stationary contact 21 and a movable contact 23 which are connected to the power source side terminals 20 and open/close the cable run; an opening/closing mechanism part 30 for opening/closing drive of both the contacts 21 and 23; a handle 31 for opening/closing operation of the opening/closing mechanism part 30; a trip bar 33 for tripping the opening/closing mechanism part 30; an overcurrent removal device 40 for driving the trip bar 33 based on a current that flows in the cable run; a leakage current detector 26 for detecting a leakage current in the cable run; and a leakage removal device 50 which is provided between the handle 31 and the overcurrent removal device 40 and drives the trip bar 33 based on a detection signal of the leakage current detector 26.SELECTED DRAWING: Figure 2 【課題】トリップバーを引外すための漏電引外し装置の吸引力を確保しつつ、小形化された漏電遮断器を得る。【解決手段】ベース１１と、このベース１１上に間隔をおいて配列され、電路に接続される電源側端子２０と、この電源側端子２０に接続され、電路を開閉する固定接触子２１および可動接点２３と、これら両接点２１、２３を開閉駆動する開閉機構部３０と、この開閉機構部３０を開閉操作するハンドル３１と、開閉機構部３０をトリップさせるトリップバー３３と、電路を流れる電流に基づいてトリップバー３３を駆動する過電流引外し装置４０と、電路の漏洩電流を検出する漏洩電流検出器２６と、ハンドル３１及び過電流引外し装置４０の間に設けられ、漏洩電流検出器２６の検出信号に基づきトリップバー３３を駆動する漏電引外し装置５０を備えた。【選択図】図２
