for Midget Fuses
Panel Mount Type
Two panel mount fuseholder designs are available for sup-
plementary 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.
SPECIFICATIONS:
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 thickness is .75".
