Eaton Specification Sheet - CB1233T120480A9
High-capacity switching performance meets 1200A current at 480V, with a 120V control circuit and three poles. This enables direct control of large motors and feeders without additional gear, improving panel density and reducing wiring complexity. Top-feed fuse configuration and fusible protection simplify installation and enhance safety, enabling rapid fault isolation in congested switchgear rooms. UL Listed protection and NEMA compatibility support regulatory compliance and resilience in challenging environments, reducing the risk of unplanned downtime. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions provide flexibility to match protection schemes and control logic without reconfiguring the cabinet. The rugged enclosure and sizeable footprint support secure installation in industrial cabinets, with Kirk provisions and auxiliary contact options for future expansion. Heavyweight construction with a 16x28x24 in footprint and 180 lb weight is designed for durable, long-life service in demanding facilities.
