The new Littelfuse Class H blocks offer many advantages over previous generations that are noted in the features and benefits section. 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

  • Indication offered on most 250V and 600V versions
  • DIN Rail releasable for all non-knife blade style fuses
  • Only one hand is required to release from DIN Rail (lock open lock closed)
  • Universal mounting holes make for easy replacement
  • Clip designs maximize electrical contact and minimize heat rise
  • Reinforcing clips are standard on all Class H fuse blocks rated 100 amp and  higher.

Note: For reinforcing clips on Class H blocks rated 30-60 amp, add "R" suffix to connector type
