KLPC series POWR-PRO® fuses provide ideal over current protection for circuits from 200 through 6000 A. KLPC series POWR-PRO® fuses specification-grade construction and performance meet or exceed the most stringent project specifications: 99.9% pure silver links, silver plated copper end bells, glass reinforced melamine bodies, o-ring seals between body and end bells and granular quartz fillers. KLPC series POWR-PRO® fuses are the only UL listed Class L fuses that provide a minimum of ten seconds time delay at 500% rated current and are also as current limiting as the fastest class L fuse on the market. On average, the peak let through currents of KLPC series fuses are 10% less than any other "time delay" class L fuse.
