The patented state-of-theart solid state design provides maximum reliability and superior performance characteristics in a true dual-element design. The use of IndicatorTM fuses reduces down-time, nuisance opening, increases safety, and can save thousands of dollars in lost production time. 18⁄10 2 21⁄4 21⁄2 28⁄10 3 32⁄10 31⁄2 4 41⁄2 5 56⁄10 6 61⁄4 7 71⁄2 8 9 10 12 15 171⁄2 20 25 30 35 40 45 50 60 70 75 80 90 100 110 125 150 175 200 225 250 300 350 400 450 500 600 NOTE: For 1/10 – 30 ampere 250 volt fuses, order nonindicating FLNR series fuses. NOTE: All FLNR_ID fuses rated 35 – 600A are Indicator fuses. NOTE: All FLSR_ID fuses rated 1 amp and above are Indicator fuses. Example part number (series & amperage): FLSR100ID 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 RECOMMENDED FUSE BLOCKS LR250 series (for FLNR_ID series fuses) LR600 series (for FLSR_ID series fuses) Refer to Fuse Block section of this catalog for additional information. FEATURES/BENEFITS I I I Reduce Down-Time — A glance at the indicating window of a FLNR_ID or FLSR_ID IndicatorTM fuse pinpoints open fuses immediately. If the window is dark, the fuse has opened. It’s that simple. No fuse testing required. Machine operators can immediately determine that there is an open fuse and request maintenance personnel to bring the proper replacement. Reduce Nuisance Opening — FLNR_ID and FLSR_ID IndicatorTM 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 IndicatorTM fuses have superior performance characteristics they can be used on a variety of applications, thus decreasing fuse inventory. I I Reduce Equipment Damage — FLNR_ID and FLSR_ID IndicatorTM fuses have superior overload and short circuit protection which can reduce equipment damage. Reduce Accidents — The FLNR_ID and FLSR_ID IndicatorTM fuses improve safety by minimizing exposure to live circuits. Unlike other forms of blown fuse indication, IndicatorTM fuses provide built-in blown fuse indication with the power on or off. No second guessing whether a light means a good or bad fuse and no current going across a blown fuse to power a lighted accessory. 28 FLNR_ID/FLSR_ID IndicatorTM Class RK5 Fuses 250/600 VAC I Dual-Element, Time Delay A F I 1/10 – 600 Amperes A K C B F D E G G E B C D H J 70-600A FIG. 1 AMPERES REFER TO FIG.
