Panel Mount Type
Two panel mount fuseholder designs are available for supplementary or
Class CC branch circuit protection. Class CC fuses have a rejection
feature on one end cap which mates with the rejection feature of
Littelfuse Class CC fuse blocks and fuseholders to prevent the
installation of fuses with lower voltage ratings or interrupting ratings.
