General Purpose Fuses General Purpose Fuses FLNR ID/FLSR ID Indicator Class RK5 Fuses 250/600 VAC Dual-Element, Time Delay 1/10 600 Amperes Applications 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 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. Its 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 doesnt matter if the power is on Littelfuse FLNR ID/FLSR ID Indicator fuses provide blown fuse or off. No second guessing whether a light means a fuse is good or indication at a glance. The patented state-of-the-art solid state design bad, and no current going across a blown fuse to power a lighted provides maximum reliability and superior performance characteristics accessory. 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.
