Eaton Specification Sheet - CB1233T120480K7
Feature → Business Impact → Application: The CB1233T120480K7 provides a high-current 1200A rating and supports 480V systems with a 120V control circuit, enabling direct control of large motors while maintaining proper trip-before-close sequencing. This reduces cabinet space needs and wiring complexity, improving overall equipment reliability in packaging lines, metal fabrication, and heavy process automation. Application-wise, the 2NO-2NC configuration supports interlock schemes and remote signaling, which enhances safety and reduces the risk of misoperation in critical line-start conditions. Another key feature is top-feed fusible protection and three-pole operation, simplifying wiring topology and enabling faster commissioning in new builds or retrofits. Industry confidence is reinforced by UL Listed certification and compatible NEMA ratings, ensuring compliance across diverse environments. The optional provisions for ground fault relay and auxiliary contacts extend fault-detection capabilities and control flexibility, lowering maintenance costs and downtime.
