Eaton Specification Sheet - CB1233B120208AXCT
High-current performance is enabled by a 1200 A amperage rating and a 208 V system voltage with a 120 V control supply. This combination supports reliable protection for large feeders and motor circuits, reducing overload risk and improving uptime in continuous operation environments. Use in motor control centers and power distribution panels where compact protective devices must handle demanding loads. UL Listed certification and NEMA ratings for 1, 3R, 4, and 12 provide robust environmental compatibility and regulatory assurance, helping to minimize compliance overhead. The bottom feed, three-pole design simplifies wiring and installation in standard panel configurations, reducing installation time and potential wiring errors. Fusible protection and optional features such as Ground Fault Relay and Blown Fuse Detection enable targeted fault isolation and rapid maintenance, lowering mean time to repair. The unit also supports control power transformer integration and auxiliary contacts, broadening protection schemes for complex MCCs and switchgear. With a durable construction and clear Eaton documentation, field technicians gain confidence during commissioning and routine servicing, improving overall equipment effectiveness.

FAQs
Installation should follow the device’s three-pole, bottom-feed configuration. Mount in a compatible enclosure (NEMA-rated) and route three wires per phase to the bottom-fed terminals. Ensure the 120 V control circuit is wired to a suitable control transformer and that the workspace provides adequate clearance for a 200 lb, 16x24x32 in assembly. Verify UL Listed requirements are met and secure auxiliary contacts as needed for your control scheme.
The switch is rated for 1200 A with a 208 V system voltage and 120 V control voltage. It features fusible protection and a three-pole, three-wire configuration, with NEMA ratings covering 1, 3R, 4, and 12 enclosures. The electrical trip uses a charge-before-close mechanism, offering reliable overload protection suitable for heavy feeders and motor loads.
Yes, CB1233B120208AXCT is UL Listed, providing standard safety certification for electrical protection devices. It supports multiple enclosure types via NEMA ratings (1, 3R, 4, 12), making it suitable for varied environments from clean, dry panels to outdoors and damp locations. Optional features further tailor protection without compromising compliance.
Optional features include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk provisions, and Auxiliary Contact Provisions. There is also support for a control power transformer to enable integrated control circuits. These options enhance fault detection, selective protection, and flexible integration into complex control schemes for MCCs and switchgear.
The rugged construction and UL/NEMA-rated protection reduce unplanned downtime by delivering reliable protection for high-current feeders and motors. Optional fault-detection features improve fault isolation, decreasing repair times. Over the life of the panel, this translates to lower maintenance costs, fewer nuisance trips, and faster commissioning, contributing to a favorable return on investment in critical manufacturing environments.
