CONSTITUTION: A breaking device is equipped with a leak alarm portion 2, a load breaking portion 1, an automatic closing portion 3, and a control portion 4. After the operation of the load breaking portion 1, when a set time t1 elapses, the automatic closing portion 3 is operated so as to conduct reclosing. The control portion 4 is provided with such a function as the reclosing is stopped when a leak alarm is again output within a set time t2 so that the load breaking portion 1 operates after the reclosing. |
