Eaton Specification Sheet - CB1233B120480A9CT
High-current capability delivers dependable protection for large motors and feeders, reducing the risk of uncontrolled fault currents and equipment damage. Business impact includes improved uptime, simplified panel design, and lower total cost of ownership in switchgear installations. This three-pole, bottom-feed configuration is ideal for motor control centers and power distribution panels in manufacturing facilities, enabling straightforward retrofit or new-build deployments. The 120V control voltage supports compact control transformers and quicker trip logic integration, improving responsiveness and ease of maintenance in control circuits while reducing wiring complexity. NEMA-rated enclosure compatibility (NEMA 1, 3R, 4, 12) ensures reliable operation in indoor, outdoor, and harsh environments, expanding installation options without compromising protection. Fusible protection provides selective coordination and rapid fault isolation, helping to minimize collateral outages and supply chain disruption. The BFD feature with three normally-on lights offers immediate visibility of trip status, expediting troubleshooting and operator safety during maintenance. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contact Provisions, and Kirk Provisions extend system protection, enable remote monitoring, and simplify integration with SCADA and modern control architectures. Industry context confirms these characteristics support compliance-driven installations while delivering measurable performance improvements in reliability, safety, and lifecycle cost.
