general purpose fuses general purpose fuses 29 www.littelfuse.com ? 2005 littelfuse ? powr-gard ? products catalog 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. 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 ap pli ca tions, 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 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. flnr_id/flsr_id indicator ? class rk5 fuses 250/600 vac ? dual-element, time delay ? 1/10 C 600 amperes specifications voltage ratings: ac: 250 volts (flnr_id); 600 volts (flsr_id) dc: 125 volts (flnr 1 ? 10 C 30a); 125 volts (flnr_id 35 C 600a); 300 volts (flsr_id) interrupting ratings: ac: 200,000 amperes rms symmetrical 300,000 amperes rms sym met ri cal (littelfuse self-certified) dc: 20,000 amperes ampere range: 1 ? 10 C 600 amperes approvals: standard 248-12, class rk5 ul listed (file no: e81895) csa certified (file no: lr29862) qpl: federal specification wf-1814 ampere ratings 1 ? 10 ** 6 ? 10 1 8 ? 10 4 8 30 80 225 1 ? 8 8 ? 10 2 4 1 ? 2 9 35 90 250 15 ? 100 1 2 1 ? 4 5 10 40 100 300 2 ? 10 1 1 ? 8 2 1 ? 2 5 6 ? 10 12 45 110 350 1 ? 4 1 1 ? 4 2 8 ? 10 6 15 50 125 400 3 ? 10 1 4 ? 10 3 6 1 ? 4 17 1 ? 2 60 150 450 4 ? 10 1 1 ? 2 3 2 ? 10 7 20 70 175 500 1 ? 2 1 6 ? 10 3 1 ? 2 7 1 ? 2 25 75* 200 600 *flsr_id only **flnr only ex am ple part number (series & am per age): flsr100id note: for 1 ? 10 C 30 ampere 250 volt fuses, order non-indicating flnr series fuses. note: all flnr_id fuses rated 35 C 600a are indicator fuses. note: all flsr_id fuses rated 1 amp and above are indicator fuses. recommended fuse blocks lr250 series (for flnr_id series fuses) lr600 series (for flsr_id series fuses) refer to blocks & holders section of this catalog for ad di tion al in for ma tion.
