RECOMMENDED FUSE BLOCKS
Littelfuse FLNR/FLSR series fuses have been the superior
UL Class RK5 dual-element time-delay fuses, and are the
most widely used class of fuses. FLNR/FLSR series fuses
provide excellent protection for all types of circuits especially
those containing motors. However, users and specifiers
should consider the significant benefits offered by Indicator
fuses. Complete information on these fuses may be found in
this section of this catalog.
LR250 series (for FLNR series fuses)
LR600 series (for FLSR series fuses)
Refer to Fuse Block section of this catalog for additional
information.
DIMENSIONS
Refer to FLNR_ID series for FLNR dimensions and
FLSR_ID series for FLSR dimensions.
APPLICATIONS
Service entrance switches
Switchboard main and feeder switches
Motor control center mains and motor branch circuits
Individual fused combination motor controllers
Distribution panelboards
Industrial control panels
Protection of fully-rated panelboards and loadcenters
All general purpose circuits

200,000 A.I.R. 鈥?Reliable interruption of all overcurrents
up to 200,000 amperes.
Faster acting short circuit protection than any non-current
limiting mechanical protective device.
Accurate and reliable 鈥?Automated, precision manufac-
tured and assembled parts ensure accurate, consistent
response to overloads and short circuits.
Reduced damage to equipment caused by heating
and magnetic forces of short circuits.
Equipment runs cooler with low-resistance
dual-element fuses.
