Class RK1 Fuses
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
• 300kA Interrupting Rating — Littelfuse self-certified to 300,000
• Reduced costs — Current-limiting design often permits use of readily
• Excellent time-delay — True dual-element construction, with separate
Ampere Ratings
* LLSRK Only.
Example part number (series & amperage): LLNRK 450.
For online ordering, use numbers LNRK and LSRK for LLNRK/LLSRK.

equipment under short-circuit conditions. Stops damaging short-
circuits faster than any mechanical protective device.
amperes as standard. Meets future trend towards higher available
short-circuit currents.
available, less costly equipment. Low resistance design reduces
power consumption and utility bills.
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.
