Eaton Specification Sheet - CB1233B120480GRAR
Three-pole, 1200 A rating delivers robust protection for large drives and heavy loads. This capability reduces nuisance trips and limits arc exposure, translating to higher uptime and longer motor life across manufacturing lines. It’s well suited for switchgear, motor control centers, and distribution panels where reliable current handling is non-negotiable. SPVR capacitor trip device delivers fast, selective tripping on single-phase faults. The business impact is shorter fault-clearing times and safer maintenance windows, lowering incident-related downtime. Applications include lighting feeders, HVAC drives, and critical process lines that require clear fault indication and dependable operation under fault conditions. Bottom feed fuse configuration simplifies wiring and minimizes installation space. The impact is easier field wiring, fewer mistake-prone connections, and a more compact footprint in crowded panels. This supports quicker commissioning and reduces labor costs during retrofit projects. Ground fault with control power transformer improves fault detection in systems with sensitive ground references. Application in facilities with stringent protection requirements; impact includes enhanced protection and compliance with safety standards, while keeping auxiliary circuits simple and traceable. NEMA ratings of 1, 3R, 4, and 12 enable versatile installation in dry, damp, and outdoors. The business value is wider deployment without modifying enclosures, and the design supports IP-related considerations where relevant in the customer's facility. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions provide extension possibilities without replacing the base unit. Dimensions and weight (16 in length, 24 in width, 32 in height; 200 lb) facilitate accurate installation planning and allows compatibility with standard mounting footprints. Warranty and support: Eaton policy 25-000; one year from installation or 18 months from shipment, ensuring service and spare parts availability.
