Refer to Fuse Block section of this catalog for additional
information.
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, generally increased levels of available
fault current and the distinct possibility that renewable fuses
may be improperly renewed, rendering them unsafe, have all
but eliminated the use of these fuses in new applications. In
addition, escalating labor costs 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
IDSR series
Indicator
fuses for circuits between 250 and 600 volts and
FLNR series for 250 volt and below circuits. Complete
information on POWR-PRO
Indicator fuses may be found in
the POWR-PRO
section of this catalog. FLNR fuses are in
this section of the catalog.
COST CONSIDERATIONS
I
When comparing the cost of using renewable fuses with the
cost of other fuses, the labor required for replacing links
and the cost of additional downtime should be included.
CAUTIONS
I
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.
I
After disassembly of fuse, examine carefully. Discard any
fuses which show evidence of weakened tube or damaged
components.
I
Remove all link residue from fuse tube.
I
Carefully clean all contact surfaces, and remove metal
spatter from all surfaces.
I
Install the proper rated fuse link and tighten all connections
securely.
I
Visually examine fuses for correct alignment of blades.
DIMENSIONS
I
For dimensions, please refer to NLN series for RLN
dimensions and NLS series for RLS dimensions.
