Description
RK1 fuses are extremely current-limiting fuses meaning they
greatly reduce or eliminate damage to circuits and equipment under
short-circuit conditions. Replacing existing Class H, K and RK5 fuses
with RK1 fuses is one of the easiest ways to immediately improve
the protection of plant workers and equipment.

250/600 VAC • Renewable • 1-600 Amperes
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

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.

CCMR
Description
The CCMR series is ideal for space saving protection
of motors up to 40 hp*. It was designed specifically to
withstand sustained starting currents of small motors. The
CCMR 60 fuse is the smallest 60 A fuse available rated at
600 V. Compared to other UL Listed fuses, Class CC fuses
are the most current-limiting, rating for rating.
Applications
