Littelfuse KLKR.250 Class CC Fuse 0.25A 200000A@600VAC Fast-Acting

Littelfuse's KLKR Series Class CC fuses represent a significant advancement in branch circuit protection, boasting an impressive 200,000 amperes interrupting rating at 600 volts. Their fast-acting design ensures rapid response to overcurrents, effectively limiting damage caused by the heating and magnetic effects of short-circuit currents, ultimately outperforming traditional mechanical protective devices. These fuses stand out for their compact size, allowing for superior protection without the excess bulk; switching from larger fuse classes can free up to 70% more panel-mounting space, making them an ideal choice for modern electrical systems. With a rating that leads to reduced current limitations for equivalent UL Listed fuses, this series is engineered for reliability and effectiveness in a space-efficient manner.
