Class H/K5 and R Fuse Blocks 250 and 600 Volt SPECIFICATIONS Voltage Rating: 250 Volts; 600 Volts Ampere Ratings: 0 – 600 amperes Approvals: UL Listed (File No. E14721) CSA Certified (File No. LR73091) RECOMMENDED FUSES Class H Blocks 250V 600V NLN RLN NLS RLS Class R Blocks 250V 600V FLNR KLNR LLNRK TLN FLSR/FLSR_ID KLSR LLSRK/LLSRK_ID IDSR Class H fuse blocks are for use with Class H/K5 fuses, which have an interrupting rating of up to 50,000 amperes. When higher interrupting ratings are required, use Class R fuses (200,000 A.I.R.) and Class R fuse blocks. Class R fuse blocks are dimensionally the same as Class H blocks, but incorporate a rejection feature which allows only Class R fuses to be inserted. FEATURES/BENEFITS Class H and Class R fuse blocks feature a one-piece fuse clip design for positive electrical contact and minimum heat rise. Side barriers provide isolation between poles. Bases on most blocks are of molded phenolic or thermoplastic, UL rated at 150° C.
