RECOMMENDED FUSE BLOCKS
LR250 series (LLNRK Series)
LR600 series (LLSRK Series)
Refer to Fuse Block section of this catalog for additional
information.
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 interrupt-
ing 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
s Extremely current limiting — Reduces damage to circuits
and equipment under short-circuit conditions. Stops
damaging short circuits faster than any mechanical
protective device.
s 300kA Interrupting Rating — Littelfuse self-certified to
300,000 amperes as standard. Meets future trend towards
higher available short circuit currents.
s Reduced costs — Current limiting design often permits
use of readily available, less costly equipment. Low
resistance design reduces power consumption and utility
bills.
s 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.
