Eaton Specification Sheet - CB4033B120208KG
High amperage rating enables 4000A fault protection, reducing arc energy and enhancing personnel safety in main switchgear. This translates to minimized downtime and longer equipment life in critical power paths; applicable to large electrical distribution panels and control centers. The three-pole design with fusible protection supports reliable interrupt capability while remaining compatible with existing Eaton and third-party switchgear deployments. Interlock functionality improves operator safety by preventing inadvertent closures, while bottom-feed wiring simplifies installation and maintenance in crowded enclosures. Ground fault protection with a transformer provides faster fault isolation, reducing outage duration in sensitive facilities. Catalog notes offer optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact provisions, enabling scalable protection. Overall, the unit fits NEMA 1, 3R, 4, 12 enclosures and UL safety standards for efficient installation and regulatory compliance.
