Features: * Industry's only UL Listed and CSA Certified fuse with a 300kA Vac interrupting rating that exceeds requirements for virtually all applications * Fast short-circuit protection provides optimal arc flash protection to reduce hazard to personnel * Easy selective coordination with all Low-Peak fuses using simple 2:1 ampacity ratio * All-purpose silver-linked fuse for both overload and shortcircuit protection for high capacity systems (mains and large feeders) * Time-delay for close sizing to load * Current-limiting action of the fuse generally affords considerable reduction in bus bracing * 300kA Interrupting rating complies with NEC(R) Sections 110.9 and 230.65 for today's large capacity systems * O-ring seals maximize pressure build-up during currentlimiting action and ensure filler retention * High grade silica sand filler accelerates response of fuse to short-circuits by having quenching effect upon the fuse arc * 99.9% pure silver links for high conductivity with low watt loss and low operating temperature at normal current levels; minimizes total clearing I2t fault energy let-through * Glass melamine tube * Silver-plated end bells Recommended Fuse Blocks -- 601 to 1200 Amps Catalog Numbers 51215 51235 Poles 1 3 No Agency listings available.
