PROBLEM TO BE SOLVED: To provide a breaker device for electric vehicle which is able to contribute to the reduction in size of a junction box, and at the same time, can be easily incorporated in the junction box. SOLUTION: In a case 11 of a breaker device 10, a pair of electrode units 12 and 12 are set up with the units 12 and 12 passing through a coil 29 for measuring a current value. The breaker device 10 is housed in a junction box, making possible the switch operation of the power supply to a drive motor from an electricity storage device, the measurement of the current value of each electrode unit 12 by means of the coil 29, and the detection of leaks based on the measured current values by means of a controller. |
