Littelfuse KLKR007 Class CC Fuse 7A Fast-Acting 200000A 600VAC 300VDC

Engineered for exceptional reliability, the KLKR Series from Littelfuse stands out with its impressive interrupting rating of 200,000 A.I.R., allowing for effective interruption of all overcurrents up to this threshold. These Class CC fuses are designed to be the smallest option available, providing branch circuit protection at 600V while delivering superior current-limiting capabilities. Unlike other UL Listed fuses, the current-limiting performance of the KLKR007 is unparalleled, significantly reducing the damaging effects associated with short-circuit currents. By offering this powerful protection in a compact form factor, these fuses optimize panel space—achieving up to 70% space savings when replacing larger Class R fuse blocks. This makes them an ideal choice for modern electrical systems that demand efficiency and reliability in crowded environments.
