Feature: The CB1233B120208CT delivers a 1200A amperage rating with fusible protection in a three-pole, three-wire configuration. This setup provides coordinated protection and rapid fault isolation, reducing arc-flash exposure and limiting downstream damage to motors and drive systems. It’s well suited for heavy-load feeders in manufacturing, metals processing, and water treatment facilities.Feature: It includes a control power transformer integrated into the switch assembly. This simplifies control wiring, delivers a stable 120V control supply, and improves the reliability of trip and close functions in panel-mounted protections. The compact transformer footprint also frees space in crowded switchgear aisles and enclosures.Feature: Bottom feed and bottom fuse configuration support straightforward mounting and easier wiring access during installation. The bottom-feed arrangement pairs with the three-wire, three-pole design to simplify interconnection and service, while the no ground fault configuration reduces grounding complications in standard installations. These attributes streamline commissioning and maintenance across HVAC, pumping, and material-handling circuits.Feature: Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions enable advanced protection schemes and monitoring. Availability of Kirk provisions supports legacy interlocks, while auxiliary contacts expand feedback to PLCs and SCADA systems. These features help meet plant safety standards and audit requirements while enabling proactive maintenance.Feature: Physical footprint is substantial at 16 in length, 24 in width, and 32 in height with an approximate 200 lb weight, designed for rugged environments and easy enclosure integration. UL Listed certification reinforces safety, and the NEMA compatibility with 1, 3R, 4, and 12 enclosures broadens installation options. The product’s dimensions and mass support stable mounting in switchgear and MCCs.Feature: Comprehensive catalog availability includes data sheets and installation notes from Eaton, with optional accessories and Kirk provisions to support compliant deployment. This documentation helps engineers validate specifications, schedule preventive maintenance, and estimate total cost of ownership.

FAQs

The CB1233B120208CT is designed for bottom-feed mounting with a three-wire, three-pole configuration. Plan for a bottom-input wiring path, connect the three lines to the designated terminals, and include the fusible protection per system requirements. Ensure the control power transformer is wired to provide 120 V for the trip/close circuitry and verify UL Listed compliance in the final assembly.
Key specs include 1200A amperage rating, 208 V system voltage, 208 V maximum voltage, 120 V control voltage, three-pole, three-wire configuration, fusible protection, and NEMA compatibility for 1, 3R, 4, and 12 enclosures. The device is UL Listed and includes options for ground fault relay and blown fuse detection for enhanced protection.
Yes. The 1200A fusible, three-pole design with a control power transformer supports reliable motor feeders and switchgear in MCCs. Its 208 V system voltage and UL Listed status, plus compatibility with common NEMA enclosures, make it suitable for demanding production lines and heavy-duty pumping or material-handling circuits.
The CB1233B120208CT carries UL Listed safety certification. It also aligns with industry expectations for enclosure compatibility (NEMA 1, 3R, 4, 12). For additional safeguards, optional features like Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection are available to meet plant safety and protection requirements.
