KLLU-1000 - Littelfuse 1000 Amp 600V AC Time Delay Current Limiting Class L Fuse, Bolt-In Mount, 200kA Interrupt Rating, UL/CSA Certified

KLLU-1000

KLLU-1000 is a Littelfuse 1000 Amp, 600V AC, time-delay, current-limiting, Class L fuse designed for robust circuit protection in demanding industrial applications.

This fuse offers reliable overcurrent protection for service switches, switchboard mains, motor control center mains, and large motor branch circuits. It features a 10-second minimum time delay at 500% of rating, reducing nuisance trips during motor starts, and provides selective coordination with other current-limiting fuses. The KLLU-1000 is an economical alternative to the KLPC series, with a slightly higher peak let-through current, and is certified for both AC and DC applications.
