ABSTRACT:
A current limiting assembly through which current may flow includes a stationary contact member, a movable contact member positioned in relation to the stationary contact member so that current flow through and from the stationary contact member into and through the movable contact member generates electromagnetic forces which create a repulsive force tending to force the movable contact member away from the stationary contact member, and a magnetic flux intensifying structure mechanically staked to said stationary contact member.
