250 V • 600 V

Description

The Littelfuse Class H/K5 and R blocks offer many benefits such as indication, snap-to-release DIN rail mounting and mounting flexibility for easier installation. Class H and Class R fuse blocks are dimensionally the same, but Class R blocks incorporate a rejection feature, which only allows Class R fuses to be inserted. Features/Benefits Accommodates a wide range of existing mounting configurations Indication offered on most 250 V and 600 V versions One hand release from DIN rail for ferrule style fuses Reinforced fuse clips are standard on all Class H and Class R fuse blocks Covers available for 100 A and lower to enhance safety Both hex and slot set screw options available on 60 Ampere, 600 Volt Class R box lugs Specifications Voltage Rating 250 V, 600 V Ampere Ratings 0–600 A Leakage Current <0.6 mA at 600 V Withstand Rating Class H: 10 kA RMS SYM Class R: 200 kA RMS SYM Materials: Base Thermoplastic Fuse Clip Tin plated copper alloy Box Lug Aluminum Pressure Plate Zinc plated steel Screw Zinc plated steel Flammability Rating UL94 V-0 Approvals UL Listed (File: E14721) CSA Certified (File: LR7316) Environmental RoHS Compliant, Lead (Pb) Free Recommended Fuses Class H/K5 Blocks – 250 V NLN Class R Blocks – 250 V FLNR/FLNR_ID, KLNR, LLNRK Class H/K5 Blocks – 600 V NLS Class R Blocks – 600 V FLSR/FLSR_ID, KLSR, LLSRK/LLSRK_ID, IDSR Web Resources Sample requests, downloadable CAD drawings and other technical information: Littelfuse.com/lfh Littelfuse.com/lfr
