**FLNR only
NOTE: For 1/10 30 ampere 250 volt fuses, order non-
indicating FLNR series fuses.
NOTE: All FLNR_ID fuses rated 35 600A are Indicator
fuses.
NOTE: All FLSR_ID fuses rated 1 amp and above are
Indicator fuses.
Example part number (series & amperage): FLSR100ID
RECOMMENDED FUSE BLOCKS
LR250 series (for FLNR_ID series fuses)
LR600 series (for FLSR_ID series fuses)
Refer to Fuse Block section of this catalog for additional
information.
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
FEATURES/BENEFITS
I
Reduce Down-Time -- A glance at the indicating window
of a FLNR_ID or FLSR_ID Indicator
TM
fuse pinpoints open
fuses immediately. If the window is dark, the fuse has
opened. It's that simple. No fuse testing required.
Machine operators can immediately determine that there is
an open fuse and request maintenance personnel to bring
the proper replacement.
I
Reduce Nuisance Opening -- FLNR_ID and FLSR_ID
Indicator
TM
fuses have superior time-delay and cycling
characteristics which can lengthen fuse life and decrease
needless opening.
I
Reduce Fuse Inventory -- Because FLNR_ID and
FLSR_ID Indicator
TM
fuses have superior performance
characteristics they can be used on a variety of applica-
tions, thus decreasing fuse inventory.
I
Reduce Equipment Damage -- FLNR_ID and FLSR_ID
Indicator
TM
fuses have superior overload and short circuit
protection which can reduce equipment damage.
I
Reduce Accidents -- The FLNR_ID and FLSR_ID
Indicator
TM
fuses improve safety by minimizing exposure
to live circuits. Unlike other forms of blown fuse indication,
Indicator
TM
fuses provide built-in blown fuse indication with
the power on or off. No second guessing whether a light
means a good or bad fuse and no current going across a
blown fuse to power a lighted accessory.
Littelfuse FLNR_ID/FLSR_ID Indicator
TM
fuses provide visual
blown fuse indication at a glance. The patented state-of-the-
art solid state design provides maximum reliability and
superior performance characteristics in a true dual-element
design. The use of Indicator
TM
fuses reduces down-time,
nuisance opening, increases safety, and can save thousands
of dollars in lost production time.
