A shorting switch eliminates arcing faults in power distribution equipment. The shorting switch includes a magnetic core having a pin member and an opening. A conductor is electrically connected between the first and second terminals and passes through the opening of the magnetic core. A switch member is pivotally mounted to the pin member of the magnetic core and is adapted to pivot toward and engage the conductor in response to arcing fault current flowing through the conductor. A third terminal is electrically interconnected with the switch member. A latch member has a first position, which holds the switch member apart from the conductor, and a second position, which releases the switch member to permit the switch member to pivot toward the magnetic core and engage the conductor in response to the arcing fault current. A solenoid unlatches the latch member in response to an activation signal.
