COOPER POWER SYSTEMS #FA4H1
Eaton provides overload protection for all indoor and underground cable distribution systems 2.4 through 34.5kV with its cooper power series NX current-limiting fuses. NX fuses are noiseless and expel no hot gases or burning particles while interrupting currents from minimum melt to maximum fuse rating (50000 A through 23kV, 35000 A through 27 and 38kV). Their currentlimiting capability greatly reduces the momentary duty on protected equipment, extending the life and, in some cases, reducing the original cost of that equipment. The ability of an NX fuse to interrupt low current faults eliminates the need for auxiliary devices to handle these troublesome current levels. An NX fuse extends system coordination because it is fast clearing and current-limiting conductor and equipment damage caused by high currents is virtually eliminated.
