徴とする断路器。 a movable contact that is moved by being operated by an operating device;
a first switch comprising an arc contact that moves in response to the movement of the movable contact while in contact with the movable contact, and slides with respect to an auxiliary contact fixed to one electrode; and a second switch that performs an opening operation when the first switch is closed.
In the switch, the part of the arc contact that slides with the auxiliary contact is made of a resistor, so that the effective resistance value of the arc contact is equal to the opening start state of the second switch. The disconnector is characterized in that the disconnector changes substantially continuously in accordance with the movement of the arc contact so that it becomes larger in the opening state of the first switch than in the opening state of the first switch.
