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 in-
serted.
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.
