General Purpose Fuses FLNR_ID/FLSR_ID Indicator® Class RK5 Fuses 250/600 VAC  •  Dual-Element, Time Delay  •  1/10 – 600 Amperes Applications General Purpose Fuses Service entrance switches Switchboard main and feeder switches Motor control center mains and motor branch circuits Individual fused combination motor controllers Distribution panelboards Industrial control panels Protection of fully rated panelboards and loadcenters All general purpose circuits Features/Benefits Littelfuse FLNR_ID/FLSR_ID Indicator fuses provide blown fuse indication at a glance. The patented state-of-the-art solid state design provides maximum reliability and superior performance characteristics in a true dual-element design. The use of Indicator fuses reduces downtime and nuisance openings, increases safety, and can save thousands of dollars in lost production time. • Reduce Downtime — A glance at the indicating window of a FLNR_ID or FLSR_ID Indicator fuse pinpoints open fuses. If the indicating strip is black, the fuse has opened. It’s that simple. • Reduce Nuisance Opening — FLNR_ID and FLSR_ID Indicator fuses have superior time-delay and cycling characteristics which can lengthen fuse life and decrease needless opening. • Reduce Fuse Inventory — Because FLNR_ID and FLSR_ID Indicator fuses have superior performance characteristics, they can be used on a variety of ap­pli­ca­tions, thus decreasing fuse inventory. • Reduce Equipment Damage — FLNR_ID and FLSR_ID Indicator fuses have superior overload and short-circuit protection which can reduce equipment damage. • Reduce Accidents — The FLNR_ID and FLSR_ID Indicator fuses improve safety by minimizing exposure to live circuits. Unlike other forms of blown fuse indication, it doesn’t matter if the power is on or off. No second guessing whether a light means a fuse is good or bad, and no current going across a blown fuse to power a lighted accessory.
