  • Stops damaging short circuits faster than any mechanical protective device
  • Reduced costs - current limiting design often permits use of readily available, less costly equipment
  • Low resistance design reduces power consumption and utility bills
  • Excellent time delay - true dual element construction, with separate non-fatiguing thermally-reversible spring loaded thermal overload element, withstands repeated surges within rated time delay without opening needlessly
  • Eliminates needless downtime caused by power surges or equipment demands
  • 200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating

Littelfuse® LLNRK and LLSRK series POWR-PRO® fuses provide superior overload and short circuit protection for service entrance, main, feeder and general purpose branch circuits upto 600 A. LLNRK/LLSRK series fuses can be installed in existing Class H fuse blocks to upgrade systems containing lower interrupting rating Class H one-time or renewable fuses.

KLSR series RK1 fuses were the earliest type of current limiting fuse developed. Their single element, silver link design enables them to provide fast acting overload and short circuit protection. When used to protect inductive loads such as motors, solenoids and transformers, KLSR series fuses must be greatly oversized to prevent opening the fuses on harmless inrush currents. In such applications, KLSR series fuses may only provide short circuit protection.
