Littelfuse CCMR04.5 Class CC Fuse 4.5A 600V 200000A Interrupting Rating Slo-Blo Time Delay

The CCMR Series from Littelfuse stands out as an exceptional solution for motor branch circuit protection, delivering reliable performance with its advanced features. Designed as true dual-element time-delay fuses, these Class CC models are engineered to be the most current limiting fuses available, effectively interrupting overcurrents up to an impressive 200,000 amperes. Their unique construction minimizes damage from short-circuit currents, working faster than conventional protective devices to safeguard both NEMA-rated and sensitive IEC motor circuit components. Additionally, the compact design of these fuses allows for superior protection while occupying significantly less space compared to other fuse classes. When replacing traditional Class R fuses with Littelfuse Class CC fuse blocks, you can achieve up to a 70% reduction in panel-mounting footprint, making them an intelligent choice for modern panel builders looking to maximize efficiency without sacrificing safety. With ampere ratings from 4.5 to 60, these fuses provide a robust solution for various applications, ensuring safe and reliable operation in demanding environments.
