Abstract
A switching device includes: a first contact; a second contact; and a fault detection circuit. The second contact includes a fixed contactor and a movable contactor. When the second contact is energized due to an operation of opening the first contact, the movable contact is separated from the fixed contact by an electromagnetic force generated by a flow of currents in opposite directions through the pair of current-carrying electrodes, and a discharge switch is formed between the movable contact and the fixed contact that are separated. The switching device further includes: a first arc runner electrically connected to the fixed contactor for driving, by an electromagnetic force, arc discharge that occurs when the second contact is opened; and a second arc runner electrically connected to the movable contactor.
