Eaton Specification Sheet - CB3033T120480GRAX6
Feature → Business Impact → Application: The CB3033T120480GRAX6 delivers three-pole, 480 V system protection with a 3000 A amperage rating, reducing the risk of overloads in high-current motor drives and switchgear. This translates to lower unplanned downtime and improved equipment life in metal fabrication, mining, and process industries. The SPVR capacitor trip device, combined with a ground-fault scheme, enables faster, safer trips on single-phase disturbances, decreasing fault-related damage and maintenance costs in packaging lines and conveyors. The top-feed, fusible configuration simplifies wiring and enhances safety during maintenance, reducing installation time and field errors in foods and beverages facilities. With UL Listed certification and broad NEMA compatibility, it easily fits legacy panels while meeting modern reliability expectations. The device’s 120 V control voltage supports standard control circuits, streamlining integration with existing MCCs and control panels.
