POWR-PRO® Fuses
CCMR Series POWR-PRO® Class CC and CD Fuses
600 VAC • Dual-Element, Time-Delay • 2/10 – 60 Amperes
circuits than would be possible if using fast-acting fuses. CCMR series
fuses provide superior protection in a fraction of the space required by
other fuse classes. For example, when 600V three pole, 30 ampere Class
R fuse blocks are replaced by Littelfuse Class CC fuse blocks, mounting
space requirements may be reduced 70% or more. This is especially
important when a panel contains control devices for many motors.
In addition to the UL Listed smaller sizes, Littelfuse CCMR series fuses
are now available in larger sizes — from 35 to 60 amperes! No other
fuse is available with this current carrying capacity in a package
this small. In fact, the 60 ampere CCMR fuse is the smallest 60A
fuse available rated at 600 volts.
Applications
CCMR series fuses are specifically designed to withstand sustained
starting currents of small motors
Provide short-circuit protection for motor branch circuits
Use with IEC- and NEMA-rated motor controllers and contactors
General purpose circuits up to 60 amps
Features/Benefits

•
Space savings — No other fuse class approved for branch circuit
protection has a 600 volt rating and 300,000 A.I.R. in such a small
package.
For space saving protection of motor circuits up to 40 HP*, we
recommend Littelfuse POWR-PRO CCMR series fuses. These fuses
are the only true dual-element, time-delay fuses that come in a small
package specifically engineered for motor branch circuit protection.
CCMR series fuses provide Type 2 “No Damage” protection to both
NEMA-rated and the more sensitive IEC (International Electrotechnical
Commission) type motor circuit components.
Extremely current-limiting — Reduces damage caused by heating
and magnetic effects of short-circuit currents. Stops damaging short-
circuit currents faster than any mechanical protective device.
Excellent time-delay — Eliminates needless downtime caused by
power surges or equipment demands. Permits selection of fuse sizes
closer to actual load conditions, which provides better protection.
300kA Interrupting Rating — Littelfuse self-certified to 300,000
amperes as standard. Meets future trend towards higher available
short-circuit currents.
Rating for rating, CCMR fuses are the most current-limiting fuses
available. They also provide superior short-circuit protection since their
time-delay characteristics permit the use of smaller fuse ratings in motor
