Eaton Specification Sheet - CB1233B120480AXCT
Three-pole, bottom-feed design delivers stable, three-wire protection for large feeders, reducing arcing risk and easing field wiring during installation. This configuration aligns with 480V system voltages and 120V control circuits, enabling straightforward integration with existing control transformers and motor controllers, improving time-to-service. Amperage rating of 1200A provides headroom for peak loads common in distribution panels, while fusible protection offers clear fault isolation and selective coordination. UL Listed certification and broad NEMA compatibility (NEMA 1, 3R, 4, 12) support safe operation in both indoor and external environments, aiding compliance documentation. Optional features such as Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions enable enhanced fault detection, maintenance visibility, and extended diagnostics, reducing unplanned downtime. Bottom feed fuse configuration simplifies retrofits by aligning with standard enclosure footprints and existing bus connections, and the 16 in depth, 24 in width, 32 in height footprint helps fit crowded switchgear layouts while maintaining serviceability.
