<p>A fuse is disclosed having terminal leads electrically connected by a fusible link, and insulated within a housing. The housing is preferably made from a material which burns cleanly and has improved ablative qualities to prevent accelerated arcing within the plasma generated by the housing during high energy periods. The desired material should have an arc resistance of about 60 to about 120 seconds, a CTI of about 250 to about 400 volts, an arc ignition resistance of greater than 120 arcs, an arc tracking rate of about 25 to about 80 millimeters per minute, and a hot wire ignition value of greater than 120 seconds. Such material being capable of increasing the voltage rating of a standard 32 volt fuse almost ten-fold to about 300 volts.</p> |
