Littelfuse KLPC450

KLPC series POWR-PRO™ 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% 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. Applications: Service switches; Switchboard mains and feeders; Bolted pressure contact switches; Motor control center mains; Large motor branch circuits; UL Listed series-rated protection for molded case circuit breaker panelboards and loadcenters. (See panelboard manufacturers' literature for recommended fuse rating); Primary and secondary protection for transformers; Protection of power circuit breakers.
