High-current protection and integrated sensing capabilities are at the core of CB1233T120480KE. The unit delivers a 1200A amperage rating with a 480V voltage rating and a 120V control voltage, all in a compact bolted assembly. The included control transformer, arc energy reduction relay, and matched CTs streamline protection coordination, reducing wiring runs and simplifying field installation for rugged industrial environments. Top feed and fuse configuration enable safer, cleaner panel layouts by bringing conductors in from the top and minimizing live-space exposure during maintenance, supporting quicker retrofits and compliant arc-flash mitigation when paired with the ARC relay. With three poles and three-wire configuration, it provides balanced protection for motors and loads, while the fusible design enhances fault isolation. This design reduces downstream equipment stress, improving uptime in demanding processes such as extrusion, milling, or packaging lines. Arc energy reduction technology lowers switching energy, improving safety and reducing PPE requirements, and matched CTs deliver accurate fault sensing for stable operation across the facility. Designed to integrate with Eaton switchgear ecosystems, CB1233T120480KE reduces procurement overhead and stocking complexity, while its footprint informs enclosure and crane-access planning.
