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
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
• 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.
Dimensions
• For dimensions, please refer to NLN series for RLN dimensions and
NLS series for RLS dimensions.
