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
in a package this small that are specifically engineered for
motor branch circuit protection.They provide Type 2 protec-
tion (no damage) to both NEMA-rated and the more sensitive
IEC (International Electrotechnical Commission) type motor
circuit components.
Because CCMR fuses are the most current limiting rating for
rating, and because their time-delay characteristics permit the
use of smaller fuse ratings in motor circuits than would be
possible with fast-acting fuses, CCMR fuses provide superior
short-circuit protection. Furthermore, they provide this
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. As a matter of
fact, the 60 ampere CCMR fuse is the smallest 60A fuse
available which is 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
I
Space savings
—
No other fuse class approved for
branch-circuit protection has a 600 volt rating and 300,000
A.I.R. in a package this small.
I
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.
I
Excellent time delay
—
Eliminates needless downtime
caused by power surges or equipment demands . . .
permits selection of fuse sizes closer to actual load
conditions
—
provides better protection.
I
300kA Interrupting Rating
—
Littelfuse self-certified to
300,000 amperes as standard. Meets future trend towards
higher available short circuit currents.
