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 |
| 200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating |
| Blown fuse indicator assembly |
| Granular quartz filling |
| Plated end caps |
| Precision formed short circuit element |
| Fiberglass reinforced pultruded body |
| Elastomeric silicone overload section |
