Littelfuse FLNR.200 Class RK5 Fuse 0.2A 250V Slo-Blo Time Delay Industrial Cartridge

The FLNR Series by Littelfuse is engineered to provide robust protection and dependable performance for various electrical applications. Specifically designed for service entrance switches, these devices are well-suited for fully-rated panelboards, loadcenters, and distribution panelboards, ensuring reliable interruption of overcurrents up to 200,000 amperes. With automated, precision-manufactured components, they offer an accurate and consistent response to both overloads and short circuits, making them ideal for all general-purpose circuits and individual fused combination motor controllers. Furthermore, this series excels in industrial control panels and switchboard main and feeder switches, delivering faster acting short circuit protection compared to non-current limiting mechanical protective devices. Rated for an interrupting capacity of 20,000 amps at 125VDC, this device features a Slo-Blo/Time Lag opening mechanism, providing the necessary time delay for effective circuit management without compromising safety. Each unit maintains a package size suitable for industrial cartridges, upholding the integrity and efficiency of key electrical systems.
