Eaton Specification Sheet - CB2033T120480GAO7
Feature: Three-pole configuration with 2 NO-2 NC contacts enables full isolation of all conductors, improving fault containment and safety. Impact: Reduces risk of accidental energization and supports complex control schemes in motor control centers and switchgear. Application: Ideal for three-wire, 480V distribution blocks where precise contact control is required. Feature: Top feed and fusible protection simplify wiring and protection coordination, cutting installation time and minimizing panel footprint. Impact: Lower total cost of ownership through fewer components and easier fault diagnosis. Application: Suitable for new builds and retrofit projects in industrial plants with high current demands. Feature: Ground fault with control power transformer option and auxiliary/provisions availability provide enhanced protection and extend diagnostics. Impact: Improves safety, enables rapid fault detection, and supports proactive maintenance programs. Application: Critical feeders, MCCs, and legacy switchboards needing fault monitoring. Feature: High ratings—2000A amperage and 480V system voltage with 120V control—coupled with rugged NEMA compatibility. Impact: Enables protection of large motors and feeders while preserving control logic integrity. Application: Heavy-industrial applications such as metal fabrication, packaging lines, and process skids. Feature: Optional features such as Ground Fault Relay, Blown Fuse Detection, Auxiliary Contacts, and Kirk provisions extend versatility. Impact: Tailors protection schemes to regulatory requirements and reduces spare-part inventories. Application: Retrofit programs and systems requiring scalable protection architectures. Industry context: This solution aligns with standard industrial control practices, offering clear installation paths, robust protection, and lifecycle cost efficiency for mission-critical power distribution.

FAQs
When installing CB2033T120480GAO7, plan for the top-feed configuration and ensure enclosure support for three-pole operation. Use wiring that matches the 2000A rating and verify compatibility with fusible protection. If ground fault or auxiliary provisions are required, select the optional accessories to simplify coordination with upstream protection as well as diagnostic clarity.
The switch features an electrical trip with a charge-before-close mechanism to prevent premature contact closing and capacitive discharge. It supports optional Ground Fault Relay, Blown Fuse Detection, and auxiliary contact provisions, enabling customizable protection sequences for motors and feeders while maintaining safe, fail-safe operation in demanding environments.
Yes. The device is rated for NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosures, aligning with common industrial enclosures used in panels and switchgear. Its three-pole design and fusible protection further support reliable performance in harsh or damp environments typical of industrial facilities.
The CB2033T120480GAO7 carries UL Listed certification, confirming compliance with safety standards for industrial electrical equipment. Eaton provides a warranty per policy 25-000, which covers one year from installation or eighteen months from shipment, whichever occurs first, offering assurance for installation reliability and long-term field performance.
You can expect reduced downtime due to improved fault isolation and fewer nuisance trips thanks to fusible protection and optional fault monitoring. The top-feed layout simplifies wiring, while the 2000A rating supports heavier loads with fewer parts. Auxiliary provisions and optional diagnostics help streamline preventive maintenance and spare-part planning, delivering measurable lifecycle savings.
