Littelfuse.com/jlls, Littelfuse.com/jlln © 2020 Littelfuse, Inc. Rev: 0618201 of 9 POWR-GARD® Fuse CLASS T – JLLN / JLLS SERIES 300/600 V ac • Fast-Acting • 1–1200 A

Description

JLLN / JLLS series fuses are less than 1/3 the size of comparable Class R fuses and are typically used for short circuit protection of drives and surge sensitive components. When rated in accordance with the NEC*, JLLN / JLLS fuses provide fast-acting overload and short circuit protection for non-inductive circuits and equipment. Features/Benefits Extremely current-limiting Compact design 200 kA interrupting rating JLLN 35–60 amperes available with PCB mounts

Applications

Variable speed drive protection Power conversion devices (inverters, rectifiers, UPS) Power supplies and power distribution units Compact mains switches Recommended Fuse Holders LFT30 series LFT60 series LSCR series for 70–800 amperes Web Resources Download TC curves, CAD drawings and other technical information: Littelfuse.com/jlln Littelfuse.com/jlls AMPERE RATINGS 1 25 70 175 450 1100 2 30 80 200 500 1200 3 35 90 225 600 6 40 100 250 700 10 45 110 300 800 15 50 125 350 900* 20 60 150 400 1000 *J L L S onl y
