Eaton Specification Sheet - CB1233B120480E
High-current capability with built-in control power transformer provides a compact, field-ready protection device. It supports 1200A at 480V with 120V control, allowing direct integration into main feeders and motor circuits without sourcing a separate transformer. The business impact is clear: fewer parts, less assembly effort, and faster commissioning in new builds or upgrades. Arc Energy Reduction Relay paired with matched CTs delivers safer operation by limiting arc flash energy and simplifying calibration. The combination lowers PPE requirements, speeds fault isolation, and improves coordination with upstream and downstream protective devices, translating to safer maintenance and more reliable operation in high-demand equipment. Bottom-feed, three-pole, three-wire design simplifies installation and reduces wiring errors. The rugged bolted contact switch supports fusible protection at 480V, enabling reliable, code-compliant switching in demanding environments. Safety and compliance are reinforced by UL Listed certification, offering assurance for panel builders and end users. The integrated features also support maintenance teams with standardized Eaton parts and documentation. In practice, this CB1233B120480E model reduces total cost of ownership by cutting external components, easing stocking with included CTs, and speeding maintenance cycles. Its compatibility with Eaton's ecosystem ensures parts availability and consistent performance across facilities.

FAQs
CB1233B120480E is designed for heavy feeders and motor control centers where high-current switching is required at 480V with a 120V control circuit. Its bottom-feed, three-pole design simplifies wiring in switchgear and MCC bays, while the included control transformer reduces external components. It’s ideal for new installations and upgrades in manufacturing, processing, and power distribution environments.
The Arc Energy Reduction Relay reduces potential arc flash energy during switching events and, with matched current transformers, provides accurate protection signals. This combination lowers PPE requirements, speeds fault isolation, and improves coordination with upstream and downstream protective devices, translating to safer maintenance and more reliable operation in high-demand equipment.
Yes. Its standardized three-pole, bottom-feed design and 480V rating align with common MCC configurations and many Eaton switchgear families. It also accepts third-party components that match the mounting footprint and CT interfaces. When integrating, verify CT ratios and fuse compatibility to ensure seamless protection coordination across devices.
The CB1233B120480E carries UL Listed certification, signaling adherence to essential safety standards for industrial equipment. This aids in panel approvals and reduces compliance risk during audits. For facilities with additional standards requirements, consult Eaton for variant options that may align with local regulations.
By consolidating power transformer, arc energy reduction, and matched CTs into a single assembly, the CB1233B120480E lowers procurement, wiring, and commissioning time, reducing labor costs. With UL Listed certification and Eaton support, maintenance planning becomes predictable, spare parts are readily available, and uptime improves, delivering a favorable total cost of ownership over the asset life.
