Eaton Specification Sheet - CB1233T120480GAX
High-current, three-pole design delivers 1200A at 480V, enabling robust protection for large feeders and motors while reducing cross-tripping in switchgear and MCCs. This translates to improved uptime, safer fault isolation, and easier coordination with plant protection schemes. The top-feed fuse configuration and 120V control voltage simplify wiring and commissioning, decreasing installation time and minimizing control-schematic errors in panel assemblies. Ground fault protection options, including a ground fault relay and blown fuse detection, enhance personnel safety and prevent collateral damage from undetected faults in electrical rooms. The UL Listed rating, combined with NEMA 1, 3R, 4, and 12 enclosure compatibility, supports reliable operation in both indoor and rugged environments. Knowledgeable procurement benefits include predictable compliance, straightforward maintenance, and a clear path to integration with auxiliary contacts and Kirk provisions for expanded control schemes.
