Industry s only UL Listed and CSA Certified fuse with a 300kA interrupting rating that allows for simple, worry-free 100kA Vdc installation in virtually any application. * Use KRP-CL fuses for current ratings from 225 to 600 amps. Fast short-circuit protection and dual-element, time-delay Agency Information: performance provide ultimate protection. CE, UL Listed, Guide JDDZ, File E4273 Reduces existing fuse inventory by up to 33% when upgrading to Low-Peak fuses. CSA Certified, Class 1422-02, File 53787, Consistent 2:1 ampacity ratios for all Low-Peak fuses make Class L per CSA C22.2, No. 248.10 selective coordination easy. RoHS Compliant Time-delay for close sizing load. Current-limiting action of the fuse generally affords Catalog Numbers (amps) considerable reduction in bus bracing.
