CCMR Fuses
Roll Over to Zoom

CCMR Series dual element, time delay fuses are recommend for space-saving protection of motor circuits up to 40 HP (download motor protection guide).

  • Only true dual-element time-delay CC fuses specifically engineered for motor branch circuit protection.
  • Provide Type II protection (no damage) to both NEMA-rated and the more sensitive IEC (International Electromechanical Commission) type motor circuit components.
  • Available in larger sizes — from 35 to 60 amperes! No other 600V fuse is available with this current carrying capacity in a package this small.
  • Compared to other UL Listed fuses, Class CC dual element fuses are the most current limiting, rating for rating.
  • Provide superior protection in a fraction of the space required by other fuse classes. — For example, when 600V three-pole, 30 A Class R fuse blocks are replaced by Littelfuse Class CC fuse blocks, panel-mounting space is reduced approximately 70%. 

Safety:

  • 200,000 A.I.R. — Reliable interruption of all overcurrents up to 200,000 amperes.
  • Extremely current limiting — Reduces damage caused by heating and magnetic effects of short-circuit currents…stops damaging short-circuit faster than any mechanical protective device.

pdf icon The Importance of Motor and Motor Circuit Protection

The importance of effective motor and motor circuit protection cannot be over emphasized. Motors are consistently the largest single cause of industrial and commercial fires, and in today’s highly automated commercial and industrial facilities, the failure of even one relatively minor motor may shut down an entire installation.
