FUSEHOLDERS

FOR 3AG, 5 x 20mm, OR MIDGET FUSES

Shock-Safe for 3AG or 5x20mm Fuses ^{PC Board Type}

Similar to Shock-Safe fuseholders shown on preceding

page, but designed for P.C. board mounting. Shock-Safe

design per IEC Standards 60127 and 60065. Two different

knob styles available for use with 3AG ( / " x 1 / ") or

5 x 20mm fuses.

APPROVALS: Recognized under the Components Program

of Underwriters Laboratories (16A, 250V).

Certified by CSA (15A, 250V).

SEMKO approved (6.3A, 250V).

VDE approved (10A, 250V).

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.
