KLPC Series UL Class L Time-Delay fuses provide ideal overcurrent protection for circuits from 200 through 6000 amperes. KLPC series POWR-PRO fuses specification-grade construction and performance meet or exceed the most stringent project specifications: 99.9 percent 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 percent 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 percent less than any other Time-delay Class L fuse.
