FLNR045ID - Littelfuse Class RK5 45A 250VAC/125VDC Time Delay Indicating Fuse

FLNR045ID

FLNR045ID is a Class RK5, 45-ampere, dual-element time-delay indicating fuse rated for 250VAC/125VDC with current-limiting protection and visual blown fuse indication. POWR-GARD series cartridge-style fuse designed for general purpose circuits including service entrance switches, switchboard mains and feeders, motor control centers, and branch circuits. Features a patented solid-state indicator window that turns black when the fuse blows, enabling fast identification without removing the fuse from the holder. The dual-element design provides advanced short-circuit and overload protection while restricting fault current to minimize circuit damage.
