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.

- Universal mounting holes make for easy replacement
