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.
APPROVALS:
Recognized under the Components Program of
Underwriters Laboratories and Certified by CSA.

Electrical:
Rated at 30 amperes for any voltage up to 600 volts.
Dielectric Strength:
4000 volts minimum.
Mounting:
Flange mounting either in front of or behind panel.
Watertight version must be front panel mounted. Maximum panel thick-
ness is .75".
