Littelfuse KLKR.500 Class CC Fuse 0.5A 600V Fast-Acting 200000A@600VAC

The KLKR Series fuses from Littelfuse stand out for their exceptional current-limiting capabilities, effectively reducing damage from both heating and the magnetic effects of short-circuit currents. These fast-acting fuses offer superior protection while requiring significantly less space—about 70% less than comparable Class R fuse blocks, making them an ideal choice for modern panel builders looking to optimize their designs. With a reliable interrupting rating of 200,000 A.I.R. and the distinction of being the smallest approved fuses for branch circuit protection at 600V, the KLKR Series is engineered to handle all overcurrents while ensuring that your systems remain safe and efficient.
