POWR-PRO® Fuses  
LLNRK/LLSRK Series POWR-PRO® Class RK1 Fuses  
250/600 VAC • Dual-Element, Time-Delay • 1/10 – 600 Amperes  
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 amperes.  
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  
All general purpose circuits  
Motors  
Transformers  
Solenoids  
Fluorescent lighting  
All system components with high in-rush currents  
Features/Benefits  
•
•
•
•
Extremely current-limiting — Reduces damage to circuits and  
equipment under short-circuit conditions. Stops damaging short-  
circuits faster than any mechanical protective device.  
300kA Interrupting Rating — Littelfuse self-certified to 300,000  
amperes as standard. Meets future trend towards higher available  
short-circuit currents.  
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.
