They provide excellent protection of motor branch circuits containing IEC or NEMA rated motor controllers or contactors. Features/Benefits • Meets UL and CSA standards • Class CC fuses are the smallest 600 V, 200,000 A.I.R. fuses approved for branch circuit protection • Rejection feature prevents use of fuses with lower interrupting ratings or voltage ratings when used with corresponding fuse holders • Extremely current limiting reduces damage caused by heating and magnetic effects of short-circuit currents Ordering Information / 1/8 15/100 3/16 2/10 1/4 3/10 4/10 1/2 / 3/4 8/10 1 1 1/8 1 1/4 1 4/10 1 1/2 1 6/10 6 10 1 10 AMPERAGE ratings 1 8/10 2 2 1/4 2 1/2 2 8/10 3 3 2/10 3 1/2 4 4 1/2 5 5 6/10 6 6 1/4 7 7 1/2 8 9 10 12 15 17 1/2 20 25 30 — — AMPERAGE Part number ORDERING number 10 KLDR 10 KLDR010.TXP Web Resources Applications For additional informations, visit: Littelfuse.com/kldr • Transformer Protection Recommended Fuse Holders L60030C Series LPSC Touch-Safe Series Dimensions Inches (mm) .25 1.50 (6.4) (38.1) .41 0-30 A (10.3) .50 (12.7) Littelfuse.com 1 of 5 .125 (3.2) © 2013 Littelfuse POWR-GARD® Products Rev: 032113 POWR-GARD® Fuse Datasheet Class CC KLDR Series FUSES Electrical Specifications Voltage Rating Interrupting Rating Agency Approvals UPC Watts Loss at 100% Rated Current (W) Watts Loss at 80% Rated current (W) Total Clearing I2T (A2 Sec) 200 kA 200 kA 20 kA 07945879252 3.56 1.40 10 • • • 300 200 kA 20 kA 07945879261 1.88 1.10 40 • • • • Ordering Number Amperage Rating AC DC KLDR01.6TXP 1-6/10 600 300 KLDR004.TXP 4 600 AC DC UL CSA RoHS KLDR07.5TXP 7-1/2 600 300 200 kA 20 kA 07945879268 1.68 0.94 1460 • • KLDR020.TXP 20 600 300 200 kA 20 kA 07945879275 2.30 1.39 1700 • • • KLDR030.TXP 30 600 300 200 kA 20 kA 07945879277 2.75 1.62 1790 • • • Current-Limiting Effects Short Circuit Current* 5,000 10,000 15,000 20,000 25,000 30,000 35,000 40,000 50,000 60,000 80,000 100,000 150,000 200,000 Apparent RMS Symmetrical current For Various Fuse Ratings 4A 315 355 380 395 405 415 420 427 438 440 455 460 470 478 6A 366 422 453 478 492 505 515 520 538 545 555 575 600 620 20 A 535 635 700 735 800 815 840 860 910 950 1010 1075 1150 1250 30 A 750 875 950 1000 1050 1125 1175 1200 1300 1350 1400 1500 1600 1750 *Prospective RMS Symmetrical Amperes Short-Circuit Current Note: Data Derived from Peak Let-Thru Curves Peak Let-Thru Curve 1000000 PEAK LET- THRU IN AMPERES 100000 30A 20A 6A - 10000 4A - 1000 100 100 1000 10000 100000 AVAILABLE FAULT CURRENT SYMMETRICAL R.M.S.
