Eaton Specification Sheet - CB4033T120208KG
High-current capability and top-feed architecture provide rapid isolation of faulted circuits, reducing arc-flash exposure and downtime during fault events. This translates to safer operations in large power-distribution panels and switchgear, with a more compact footprint for MCCs and feeder lines. The interlock and charge-before-close mechanism enhance safety during servicing, preventing accidental energization and improving changeover reliability for critical equipment. Ground-fault protection with a control transformer option adds an extra layer of safety, helping facilities meet protective-relay standards and reduce nuisance trips. NEMA ratings of 1, 3R, 4, and 12 ensure dependable performance in indoor, damp, washdown, and outdoor environments, aligning with harsh industrial conditions. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, and Auxiliary Contact Provisions let you tailor the protection scheme to specific line criticalities, reducing maintenance events and extending component life. Compatibility with Eaton catalog notes and standard top-feed configurations simplifies installation and future expansion, delivering faster commissioning and predictable lifecycle costs.
