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.
