Eaton Specification Sheet - CB2033T120480KAX5
High-current performance is the core feature of the CB2033T120480KAX5. With a 2000A amperage rating and 480 V system voltage, this switch provides direct control for large motors and high-load feeders without requiring intermediate machinery. The result is tighter protection coordination, reduced fuse replacements, and lower energy losses in the switchgear assembly. In practice, engineers appreciate the straightforward top-feed design that speeds installation in new builds or retrofit projects. Reliability comes from the three-pole, three-wire configuration and the 1NO-1NC contact arrangement. This arrangement delivers a clean break path for both normally open and normally closed circuits, improving fault isolation and diagnostics. The top feed and fusible protection options simplify wiring block design and enable quick field servicing, minimizing downtime during maintenance or commissioning of heavy electrical systems. Safety features include interlock logic and a Blown Fuse Detection (BFD) option, with optional ground fault relay and auxiliary contact provisions available. The interlock prevents accidental closure, while BFD with no lights ensures clear fault signaling. Together, these options support lockout-tagout procedures and compliance with plant safety standards in manufacturing, mining, and power generation applications. Durability and compliance are reinforced by UL listing and broad NEMA enclosure compatibility (1, 3R, 4, 12). The device is designed for rugged environments, with fusible protection and protective ratings that align with enterprise safety and reliability goals. This combination reduces integration risk for OEMs and service teams while supporting ongoing regulatory compliance. Installation and lifecycle considerations include a substantial footprint (16 in length, 28 in height, 24 in width) and a 180 lb weight, designed for fixed mounting in dedicated switchgear bays, with optional ground fault and auxiliary provisions facilitating future upgrades. Warranty coverage follows Eaton’s policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first, ensuring long-term support for mission-critical equipment.

FAQs
When retrofitting CB2033T120480KAX5 into existing panels, ensure a compatible top-feed arrangement, three-wire connections, and space for a 16 in by 28 in by 24 in footprint. Verify a 120 V control circuit and 480 V system voltage compatibility, along with the 1NO-1NC configuration. Confirm UL Listed status for compliance and plan for optional ground fault or auxiliary contacts if required.
The 2000A rating requires appropriately sized bus, conductors, and protective devices to coordinate with the switch. Use matching fusing and circuit protection to prevent nuisance trips, ensure proper heat dissipation, and maintain safe clearance. This rating supports direct control of large motors, reducing intermediate devices and simplifying protection schemes while preserving safe shutdown behavior.
Yes.
