Description
Littelfuse RLN and 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, have rendered them unsafe.
The use of these fuses in new applications is prohibited by law.
Applications
• General purpose residential and commercial circuits with
little or no motor load.
• Replacement only
Features/Benefits
• Replaceable fuse links
• 10 kA Interrupting Rating
Specifications
Voltage Ratings: AC: 250 V (RLN); 600 V (RLS)

Ampere Range: 1 – 600 A
Approvals: Standard 248-6, Class H
UL Listed (File No. E81895)
CSA Certified (File No. LR29862)
Fuse Links: To order, specify LKN (250V) or LKS (600V) plus

Renewable Fuse Guide for Proper Usage
• 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.
• Renewable fuses and links are not recommended for
new applications.
