Eaton Specification Sheet - CB2533T120480AX
The CB2533T120480AX provides a 2500 A amperage rating at 480 V, enabling direct switching of large motors and reducing the need for multiple contactors. This consolidation lowers installation time and long-term maintenance costs, while improving fault isolation in switchgear and motor control centers. The top feed, fusible configuration simplifies wiring and enhances protection coordination, helping you meet utility and safety standards in harsh industrial environments. The charge-before-close mechanism improves safety during energization, limiting arcing and wear on switchgear components, which translates into longer equipment life and fewer unplanned outages. Optional Ground Fault Relay, Blown Fuse Detection, Auxiliary Contact Provisions, Kirk provisions, and Single Phase Protection address common automation and safety requirements without multiple add-on devices. UL Listing and compatibility with NEMA 1, 3R, 4, and 12 enclosures support regulatory compliance and easier procurement. Installation and service become more straightforward when you standardize on a high-capacity, modular protection solution.

FAQs
Yes. CB2533T120480AX is designed for 480 V systems and top-feed, fusible protection in switchgear and motor control centers. It supports three-pole, three-wire configurations and is UL Listed, ensuring safe integration with common industrial panels. Verify enclosure rating (NEMA 1, 3R, 4, 12) and space for the 28 in W x 28 in H x 17 in D footprint during planning.
Key specs are 2500 A amperage rating, 480 V system voltage, and a 120 V control voltage. The three-pole, three-wire design, top-feed configuration, and fusible protection enable direct motor switching with reliable coordination. The charge-before-close mechanism improves startup safety, reducing arcing and extending switchgear life in demanding industrial environments.
Yes. Optional features include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contact Provisions, and Kirk Provisions. These options support enhanced protection schemes, selective tripping, and easier integration with controllers or PLCs, helping you meet specific safety and diagnostic requirements without adding multiple devices.
CB2533T120480AX carries UL Listing and is compatible with NEMA-rated enclosures: 1, 3R, 4, and 12. This combination provides compliance with common industrial safety standards and enables use across a wide range of control panels and switchgear in manufacturing facilities, data centers, and process industries.
By consolidating high-current switching, protection, and optional diagnostics into a single, UL-listed device, you reduce assembly complexity and potential failure points. Fewer components mean lower maintenance labor and spare parts costs, faster commissioning, and improved uptime, contributing to a favorable total cost of ownership over the system’s life cycle.
