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.  
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 additional 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  
We recommend the use of POWR-PRO® IDSR series  
Indicatorfuses 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.  
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.
