" LIT " LLNRK-2-1/2 LITTLEFUSE

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:

• 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.
