General Purpose Fuses
RLN/RLS Class H Fuses
250/600 VAC • Renewable • 1 – 600 Amperes
and increasing automation, which makes downtime very expensive,
have greatly reduced or eliminated the cost savings attributed to
renewable fuses.
We recommend the use of POWR-PRO® FLSR_ID series Indicator®
fuses for circuits between 250 and 600 volts and FLNR_ID series for
circuits 250 volts and below. Complete information on POWR-PRO
Indicator fuses may be found in the POWR-PRO fuse section of this
catalog. FLNR fuses are in this section of the catalog.
Cost Considerations
• When comparing the cost of using renewable fuses with the cost of
other fuses, the labor required for replacing links and the cost of addi-
tional downtime should be included.
Cautions
• Renewable fuses should only be used where short-circuit currents
are known to be less than 10,000 amperes, and where correct
replacement of open links is assured.
• After disassembly of fuse, examine carefully. Discard any fuses
which show evidence of weakened tube or damaged components.
• Remove all link residue from fuse tube.
• Carefully clean all contact surfaces, and remove metal spatter from
all surfaces.
• Install the proper rated fuse link and tighten all connections
securely.
• Visually examine fuses for correct alignment of blades.
Littelfuse RLN/RLS series renewable fuses are a quality product that
have traditionally been used to provide low cost protection of general
purpose feeder and branch circuits where available short-circuit currents
do not exceed 10,000 amperes. However, increased levels of available
fault current and the possibility that renewable fuses may be improperly
renewed is a potential safety hazard. In addition, escalating labor costs
Dimensions
• For dimensions, please refer to NLN series for RLN dimensions and
NLS series for RLS dimensions.

To order, specify LKN (250V) or LKS (600V) plus
ampere rating.
FUSE LINKS:
*These ampere ratings require two links per fuse.
**RLS Only.
Example part number (series & amperage): RLN 20
Recommended Fuse Blocks
LH250 series (for RLN series fuses)
