<p>An enclosed, non-vented expulsion fuse structure includes a generally tubular fuse holder for receiving a universal fuse link. The fuse holder includes an inner tube lining of organic material of the type which decomposes in the presence of an arc which results when the fusible element of the fuse link melts or blows. The decomposition of the organic material evolves a turbulent, high-pressure, high-temperature permanent gas which acts to extinguish the arc. The fuse holder is enclosed except at one end thereof wherein the gas is discharged from the fuse holder through an opening at said one end. The opening is closed into an enclosed chamber which receives the gas discharged from the fuse holder. The enclosed chamber has a thermal-quenching medium disposed therein.</p> |
