Eaton Specification Sheet - CB4033T120208KCT
Feature → Business Impact → Application: High-current capability of 4000A with 208V system voltage supports heavy motor loads and high-demand feeders, delivering reliable performance and reducing thermal stress on downstream equipment. This translates to fewer nuisance trips, lower energy waste, and improved line-side protection in manufacturing lines and material handling. Feature → Interlock with control power transformer provides a safe, controlled sequence for charging and closing, minimizing the risk of arcing and operator injury during maintenance or startup in aerospace, automotive, or process industries. Feature → Top feed, fusible protection, and three-pole, 3-wire design simplify wiring schemas and enable straightforward integration into existing power distribution layouts, improving installation speed and reducing panel space requirements in centralized control rooms. Feature → NEMA 1, 3R, 4, 12 ratings extend enclosure compatibility from indoor panels to weather-exposed and corrosive environments, increasing uptime in outdoor substations, remote facilities, or harsh manufacturing floors. Feature → Optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection address evolving safety standards and predictive maintenance programs, decreasing unplanned outages and enabling proactive asset management. Feature → Comprehensive specifications including 17" depth, 28" height, 40" width, and 390 lb weight, offer a clear footprint for panel planning and spare-parts budgeting, supporting long-term lifecycle planning across large-scale installations.

FAQs
Install with the top feed configuration per Eaton guidelines, ensuring correct phase alignment for the three-pole circuit. Verify control voltage is 120 V and system voltage is 208 V, then connect the fusible protection path and interlock wiring to the control power transformer as specified. Use the listed enclosure ratings to select appropriate mounting and keep the assembly within the recommended space for service access.
Its 4000A amperage rating and three-pole, three-wire design deliver robust performance for heavy-duty motors and feeders. The fusible protection configuration provides reliable fault isolation, while the 208 V system voltage and 120 V control voltage support seamless integration with standard industrial control schemes and switchgear, reducing drive-side losses and improving overall system reliability.
Yes. The product is UL Listed, confirming safety compliance, and supports NEMA ratings 1, 3R, 4, and 12, enabling use in a wide range of indoor and rugged environments, including damp or outdoor conditions when paired with appropriate enclosures.
Catalog notes indicate optional ground fault relay, blown fuse detection, single phase protection, and auxiliary provisions are AVAILABLE. These options simplify building compliance with safety standards and support predictive maintenance programs, helping reduce unplanned outages and extend asset life.
The unit occupies 17 inches in depth, 28 inches in height, and 40 inches in width, with an approximate weight of 390 pounds.
