LLNRK Series - UL Class RK1 Dual Element Time-Delay Fuse

Brand: Littelfuse, Inc

Littelfuse LLNRK 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 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.
Features
  • Extremely current limiting - Reduces damage to circuits and equipment under short-circuit conditions. Stops damaging short circuits faster than any mechanical protective device
  • 300 kA 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
