The unique design of Littelfuse’s compact SLC series Class G fuses
provide additional time-delay over competitive products which increases
system reliability.
Compact Class G fuses were the first fuse series to approach midget fuse
dimensions and meet NEC requirements for branch-circuit protection.
The unique dimensions of SLC series Class G fuses prevents insertion of
lower voltage fuses in Class G fuse holders. The fuse’s varying length
prevents insertion of higher ampere rated fuses in fuse holders designed
for lower ampere ratings.
Class CC fuses are replacing Class G fuses in many new designs. Class
CC fuses’ superior time delay plus higher voltage and interrupting
ratings meet the needs of modern circuits. Littelfuse’s introduction of
POWR-PRO® CCMR series fuses, with ratings up to 60 Amperes for
providing branch circuit protection, are accelerating this trend.
Safety:
100,000 A.I.R. — Reliable interruption of all overcurrents up to 100,000 amperes.
Current limiting design reduces damage to equipment caused by heating and magnetic effects of short circuit currents.
Medium time-delay allows fuses to be sized
closer to actual equipment requirements — no need to greatly oversize to
withstand harmless equipment or system surges.
Reduced Downtime:
Medium time-delay may reduce downtime caused by power surges or equipment demands.
