Eaton Bussmann 8CLPT-5E High-Voltage Cartridge Fuse

The Eaton Bussmann 8CLPT-5E is a high-voltage, single-barrel current-limiting cartridge fuse from the Bussmann CLPT family, designed for medium-voltage protection up to a maximum of 8.3 kV in distribution equipment. It carries a 5 A rating and a 50 kA interrupt rating, and the “5E” designation indicates an indicating, E-rated fuse that provides fault indication at a glance, making it suitable for installations where visible status matters. This clip-mount unit measures about 9.5 in length by 1.6 in width by 1.6 in height, and it uses a glass-resin casing filled with silica sand with a pure silver element, delivering reliable fast clearing in demanding environments. The fuse is Class E (E-rated) and compatible with Bussmann CLPT fuse holders used in distribution panels and transformer protection schemes in medium-voltage circuits. An indicating feature provides a visual indication when the fuse has operated, aiding quick fault verification during service.
