ABSTRACT:
An electrically conductive expulsion fuse manifold and bus for connecting and mounting a plurality of fuses which upon operation expel gases into the manifold is shown and described. The expulsion fuses are attached to the manifold by means of clamps, flanges, and/or threaded connections. Each expulsion fuse includes an expendable cap which may be blown off into the manifold under high magnitude capacitor discharge currents and/or fault currents for safe double-vented fuse operation. The manifold may also be non-conductive where electrical isolation is required and where a separate electrically conductive bus is employed.
