Abstract
Fault breaking contactors are disclosed. In an embodiment, an electromechanical switching device includes one or more terminals; a moveable contact; and an actuator assembly for moving the moveable contact between a closed position in which the moveable contact contacts the one or more terminals and an open position in which an air gap is maintained between the moveable contact and the one or more terminals; and a dynamic air gap mechanism configured to increase the air gap beyond that of the closed position in response to a fault current.
Claims20
An electromechanical switching device comprising:
- one or more terminals;
- a moveable contact;
- an actuator assembly for moving the moveable contact between a closed position in which the moveable contact contacts the one or more terminals and an open position in which an air gap is maintained between the moveable contact and the one or more terminals;
- and
- a dynamic air gap mechanism configured to increase the air gap beyond that of the open position in response to a fault current.
An electromechanical switching device comprising:
- a plurality of terminals with fusing-tips;
- a moveable contact for connecting with the fusing-tips of the plurality of terminals;
- and
- an actuator assembly for moving the moveable contact into contact with the fusing-tips of the plurality of terminals.
An electromechanical switching device comprising:
- one or more terminals;
- a moveable contact;
- an actuator assembly for moving the moveable contact between a closed position in which the moveable contact contacts the one or more terminals and an open position in which an air gap is maintained between the moveable contact and the one or more terminals;
- and
- an overtravel spring supporting the actuator assembly that acts as a stop on the actuator assembly and positions the actuator assembly relative to a solenoid magnetic circuit.
