Abstract
An electrical fault protective device for providing power interruption in electrical circuits rated up to 10,000 amperes and above. The device comprises a single- or double-vented expulsion-type fuse, connected at one vented end to a hollow bus and at the other end to a conductive expansion chamber for a double-vent fuse or an electrical contact for a single-vent fuse. A spring located in the hollow bus is attached to the fusible link for pulling the fusible link from the fuse tube to rapidly extinguish the arc when the fuse blows. The fuse tube is also retractable into the hollow bus when the fuse blows to provide a visual indication of fuse operation and to relieve the dielectric stress on the fuse tube.
