Terminals: Width (± 0.06), Thickness (± 0.03) Ratings Features: • Volts • Industry’s only UL Listed and CSA Certified fuse • 600Vac (2001-6000A) with a 300kA interrupting rating that allows for • 300Vdc (3000A) simple, worry-free installation in virtually any application. • Amps 2001-6000A • • Fast short-circuit protection with time-delay IR performance provide ultimate protection. • 300kA Vac RMS Sym. (2001-6000A) • Consistent 2:1 ampacity ratios for all Low-Peak • 100kA Vdc (3000A) fuses make selective coordination easy. • Agency information Time-delay for close sizing load. ® • Current-limiting action of the fuse generally • UL Listed, Guide JDDZ, File E4273 affords considerable reduction in bus bracing. ® • CSA Certified, Class 1422-02, File 53787, • All-purpose silver-linked fuse for both overload Class L per CSA-C22.2 No. 248.10 and short-circuit protetion for high capacity • CE systems (mains and large feeders). • RoHS compliant • O-ring seals maximize pressure build-up during current-limiting action and ensure filter retention. • High-grade silica sand filler accelerates response of fuse to short-circuits by having quenching effect on the fuse arc. • 99.9% pure silver links provide low watt loss with low operating temperature on normal 2 current levels and minimizes total clearing I t fault energy left-through.
