Description

The Littelfuse Class H/K5 and R blocks offer many benefits

such as indication, snap-to-release DIN rail mounting and

universal mounting holes. 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.
