SLC040 - SLC Series

slc
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.
