Abstract
According to an embodiment, when a switchgear operating state is shifted from a close state to a cutoff state, a solenoid lever is pushed and rotated by a plunger of an electromagnetic solenoid for cutoff so that the solenoid lever rotates in a direction opposite from the direction of the urging of a solenoid-lever return spring. A trigger roller pin and the solenoid lever become disengaged from each other, an eccentric pin and a trigger lever are rotated by the urging force from a latch leading end become disengaged from each other, whereby a latch lever is rotated by the released energy of a cutoff spring.
