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.SpecificationsAmpere Rating (A)0. 6VAC (V)600VDC (V)250Interrupting Rating200000A@600VACOpeningSlo-Blo/Time Lag (T)/Time DelayPackage SizeClass CC
