Littelfuse KLKR006 Class CC Fuse 6A 600VAC 200000AIR Fast-Acting

The KLKR006 fuse from Littelfuse is engineered for exceptional performance in electrical protection, specifically designed to handle demanding conditions while conserving space. With an impressive interrupting rating of 200,000 amperes at 600 VAC, it effectively limits damaging short-circuit currents faster than traditional mechanical devices, safeguarding your equipment from the adverse effects of overheating and magnetic forces. This Class CC fuse is the smallest 600V fuse approved for branch circuit protection, allowing for significant space savings—up to 70%—when replacing conventional fuse blocks, making it an ideal choice for modern panel builders looking to optimize layout without compromising on safety. With a fast-acting opening mechanism and a current-limiting capacity unmatched within its class, the KLKR series offers reliable interruption of all overcurrents, ensuring robust protection in a compact and efficient design.
