Abstract:
A circuit interrupting device for use with an electrical power distribution system, comprising:a circuit interrupter including a primary contact and a movable contact movable relative to said primary contact between a closed position allowing current to pass through said circuit interrupter and an open position separating said contacts and preventing current from passing through said circuit interrupter, said circuit interrupter being ungrounded; an actuator coupled to said circuit interrupter, said actuator including a shaft coupled to said movable contact of said circuit interrupter for substantially simultaneous movement without insulation being disposed between said shaft and said movable contact, said shaft moving said movable contact from said closed position to said open position upon occurrence of a fault current, said actuator being ungrounded; and an electronic control electrically connected to said actuator and communicating with said actuator to trigger said shaft to move said movable contact of said circuit interrupter from said closed position to said open position, said electronic control being ungrounded.
