Eaton Specification Sheet - CB4033T120480AXCT5
The CB4033T120480AXCT5 delivers a 4000 A amperage rating at a 480 V system with a 1NO-1NC contact configuration. This combination supports high-current feeders and motor circuits in heavy industrial switchgear, reducing the number of devices required and simplifying protection coordination. Top feed and fusible protection simplify wiring and fuse coordination in crowded control panels, while the three-pole arrangement ensures predictable fault clearing in demanding environments. UL Listed certification provides safety compliance and helps meet procurement and regulatory requirements, with compatibility across NEMA 1, 3R, 4, and 12 enclosures for versatile indoor-outdoor use. Optional ground fault relay, blown fuse detection, single-phase protection, Kirk provisions, and auxiliary contact provisions offer installation flexibility and extended monitoring capabilities. Control power transformer compatibility streamlines control circuit integration and supports scalable upgrades as plant needs evolve. This combination of rugged construction and modular options translates to reduced downtime, easier maintenance, and a lower total cost of ownership for mission-critical power systems.
