Claims

[Scope of utility model registration request]

A movable electrode that has a fixed side electrode part that integrally includes a main contact and a fixed arc contact, and a movable contact that is provided opposite to this fixed side electrode part and that electrically opens and closes to the main contact. In the disconnector, the movable side electrode part is configured to electrically contact the fixed arc contact of the fixed side electrode part when the movable contact is separated from the main contact to interrupt the electrical circuit. A movable arc contactor is provided, and the fixed arc contactor contacts the movable arc contactor when the electric circuit between the movable contactor and the main contactor is broken, and the movable arc contactor is disconnected. A disconnector characterized by being provided with a resistor whose resistance value increases with operation.
