Littelfuse KLKR.750 Class CC Fuse Fast-Acting 0.75A 600V 200000A.IR

The KLKR Series from Littelfuse showcases advanced engineering with its remarkable capacity to interrupt overcurrents up to 200,000 amperes, providing a vital safeguard for electrical systems. Notably compact, these Class CC fuses offer superior protection while occupying significantly less panel-mounting space—up to 70% less than traditional Class R fuse blocks. The fast-acting design enhances their efficiency, limiting damage from short-circuit currents faster than any mechanical protection could, while still adhering to stringent UL Listings. With an ampere rating of 0.75 and an impressive interrupting rating of 200,000 A at 600 VAC, these fuses represent the pinnacle of reliability and performance for branch circuit protection in high-demand applications.
