FLNR-500 - Littelfuse Class RK5 500A 250VAC Time Delay Dual Element Fuse

FLNR500

FLNR-500 is a Class RK5 dual-element time-delay fuse rated for 500 amps at 250VAC/125VDC, designed for general purpose circuit protection in industrial and commercial applications. This cartridge-style fuse features a dual-element design that provides advanced short-circuit and overload protection with current-limiting capabilities to restrict fault current and enhance circuit safety. The time-delay characteristic allows temporary inrush currents while protecting against sustained overloads, making it ideal for motor circuits, transformers, switchboard feeders, and service entrance applications.
