Eaton Specification Sheet - CB3033T120480GRAR
High-current capability translates to real-world protection for large motors and feeders, reducing downtime and improving overall plant reliability. The CB3033T120480GRAR employs a three-pole bolted pressure contact switch with a charge-before-close mechanism, ensuring reliable fault clearance and controlled switching in demanding applications. In practice, this means fewer false trips and better coordination with upstream protection, enabling faster recovery after faults and lower maintenance costs. The capacitor trip device (SPVR) integrated with BFD indicators supports single-phase protection while providing clear feedback to operators, which improves operator confidence during commissioning and normal operation. Ground fault with control power transformer adds an extra layer of safety for personnel and equipment, particularly in panels with sensitive control circuits. With optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions, it adapts to evolving protection schemes without major redesigns. This adaptability benefits industries such as power distribution, packaging, and heavy manufacturing where protection schemes must evolve with line upgrades and component replacements. Overall, the CB3033T120480GRAR offers robust protection, simplified maintenance, and compatibility with existing Eaton switching devices and accessories, delivering measurable efficiency gains and a lower total cost of ownership over the life of the installation.
