Breaker
A breaker (1) is provided with: a transmission mechanism (30) for changing a cut-off state to a power-on state by moving a needle (6) in association with the movement of a plunger (23) of an electromagnetic solenoid (20); and a tripping mechanism (50). The plunger (23) reaches a first position where...

| Zusammenfassung: | A breaker (1) is provided with: a transmission mechanism (30) for changing a cut-off state to a power-on state by moving a needle (6) in association with the movement of a plunger (23) of an electromagnetic solenoid (20); and a tripping mechanism (50). The plunger (23) reaches a first position where the movement of the plunger (23) is restricted before a toggle mechanism which includes an insulating bar (33) and a lever (32) of the transmission mechanism (30) reaches a dead point. The tripping mechanism (50) engages the transmission mechanism (30) and maintains the power-on state, in a situation where the plunger (23) has reached the first position and then has retreated so as to be located at a second potion. |
