Document Type and Number:
Japanese Patent JP6921421
Kind Code:
B2
Abstract:
To provide a circuit breaker having good responsiveness at the time of blockage.SOLUTION: A circuit breaker includes a contact part of a circuit, an attraction body becoming an electromagnet by the current of the circuit, and a movable body capable of switching to a holding state for holding the closed state of the contact part and opposing the attraction body with a gap, and a release state for moving to the attraction body side and making the contact part openable by releasing the holding of the contact part in the closed state. The attraction body and the movable body have an attraction side facing surface and a movable side facing surface placed oppositely to each other, and the attraction side facing surface and the movable side facing surface have contact parts coming into contact with each other in the holding state and a contact/detachment part separating from each other. By rotation of the movable body having a rotation origin at a position deviated from the contact part of the movable side facing surface, the contact/detachment parts of the movable side facing surface and the attraction side facing surface is separated. The attraction body is rotatable with a position deviated to the other side from the contact part of the attraction side facing surface as a rotation origin, and the attraction body is energized to the movable body side at a position deviated to the rotation origin side of the attraction body from the rotation origin of the attraction body.SELECTED DRAWING: Figure 2
