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 up to 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.
- Applications
- Features
All general purpose circuits |
Time-Delay |
Extremely current limiting - reduces damage to circuits and equipment under short circuit conditions |
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 |

Blown fuse indicator assembly |
Granular quartz filling |
Plated end caps |
Precision formed short circuit element |
