Japanese Patent JP2018006201
Kind Code:
A
Abstract:
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
