Abstract
Electric current is limited in a current interruption device including two stationary contacts with terminals and a bridging contact movable toward and away from a position bridging the stationary contacts by a conductor connected to each of the stationary contacts and an interconnection of the ends of the conductors remote from the stationary contacts to provide a parallel current path other than the current path for the arc with the current being interrupted when the bridging contact moves away from its bridging position at a value of the current flowing through the conductors such that upon interruption of the current therethrough the voltage across the stationary contacts is sufficient to generate an arc therebetween with the arc travelling along the conductors away from the stationary contacts by the magnetic field generated from the current flowing through the conductors.
