A recloser for use with an electrical power distribution system including a circuit interrupter including a primary contact and a movable contact movable relative to the primary contact between a closed position allowing current to pass through the circuit interrupter and an open position separating the contacts and preventing current from passing through the circuit interrupter. An actuator is coupled to the circuit interrupter. The actuator includes a movable shaft coupled to the movable contact of the circuit interrupter for substantially simultaneous movement therewith and without insulation being disposed between the movable contact and the movable shaft. An electronic control is electrically connected to the actuator. The electronic control communicates with the actuator upon occurrence of a fault current to trigger the shaft to move the movable contact of the circuit interrupter from the closed position to the open position and to trigger the shaft to reclose the movable contact from the open position to the closed position upon termination of the fault current.

Electrical circuit interrupting device

A circuit interrupting device for use with an electrical power distribution system including a circuit interrupter having a closed position allowing current to pass through the circuit interrupter and an open position preventing current from passing through the circuit interrupter. An actuator is electrically and mechanically coupled to the circuit interrupter. The actuator moves the circuit interrupter between the closed and open positions upon occurrence of a fault current. First and second terminals are electrically connected to the circuit interrupter and are adapted for electrical connection to the power distribution system, defining a current path between the first terminal, the circuit interrupter, and the second terminal, allowing current of the power distribution system to pass through the current path so that the potential of the circuit interrupter is the same as the potential of the power distribution system. The circuit interrupter and the actuator are not mounted in a grounded container, and the first terminal, the circuit interrupter, the actuator, and the second terminal are ungrounded.
