ABSTRACT:
High-speed breaker for an electric circuit, including a fixed contact, movable contact and a movable holder for the movable contact. An actuating rod is reciprocally movable toward and away from the fixed contact between first and second positions. A head is connected to the actuating rod. In the first position of the actuating rod, the head engages with the movable holder to cause the movable contact to engage with the fixed contact. In the second position of the actuating rod, the movable contact is disengaged from the fixed contact. A release member connected to the head is operative in response to overcurrent passing through the circuit when the actuating rod is in the first position, to disengage the movable holder from the head to disengage the movable contact from the fixed contact. An extension of the actuating rod is located between the engaging position of the movable holder with the head and the connecting position of the release member to the head.
