Eaton Specification Sheet - CB1233B120208KG
High-current capability translates to a single-point main switch for feeders up to 1200A, reducing the need for parallel devices and simplifying protection schemes. This level of current handling improves reliability and can lower total installed cost in data centers, plants, and heavy manufacturing environments. Used in substations and switchgear assemblies to protect motors and feeders, it streamlines design and maintenance. System voltage compatibility with 208V systems and 120V control circuits ensures seamless integration into common industrial power architectures, reducing wire counts and wiring errors. The three-pole, three-wire configuration provides complete phase control and arc suppression, enhancing personnel safety and system protection. Bottom feed and fusible protection simplify wiring layouts and fuse coordination, enabling quicker installation and easier fuse replacement during maintenance windows. UL Listed, with robust NEMA protection (1, 3R, 4, 12), delivers proven rugged performance in diverse environments, aligning with modern compliance expectations. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact provisions offer enhanced fault sensing and control flexibility, supporting predictive maintenance strategies and faster fault isolation. This combination supports reliable interlock operation in switchgear and motor control centers while delivering predictable, repeatable performance across shifting workloads.
