The CCMR Series dual-element, time-delay fuses carry the Littelfuse POWR-PRO® advanced technology designation. These fuses are ideal for space-saving protection of motor circuits up to 40 hp and are specifically designed to withstand sustained starting currents of small motors. Their superior time-delay capability eliminates needless downtime caused by power surges or equipment demands. They provide Type 2 “No Damage” protection for both NEMA- and IEC-type motor circuit components. Rating for rating, CCMR Series fuses are the most current-limiting fuses available. POWR-PRO performance brand products offer advanced technology protection features such as high-interrupt capabilities up to 300kA, low energy losses, and superior current limitation. 300kA short-circuit testing for POWR-PRO products is self-certified and conducted at a nationally recognized testing laboratory.
