ABSTRACT:
A current limiting apparatus includes bridging electrical contacts forming a first current path across a gap in a conductor, a trigger for breaking said first current path in response to an excessive or rapidly changing level of current on said conductor, a fast acting fuse forming a second current path across said gap, for maintaining a conductive path across said gap for a predetermined length of time after breaking of said first current path, to allow the bridging electrical contacts to separate a sufficient distance from said gap to preclude arcing thereacross, and an auxiliary resistor connected across said gap to provide a relatively high resistance conductive path for current in the conductor after said fuse has blown.
