Eaton Specification Sheet - CB1633T120480A
High-capacity protection with 1600A amperage rating and 480V system voltage enables the CB1633T120480A to handle large motor loads and peak demand without frequent panel changes, reducing downtime and installation complexity in switchgear environments. This translates to improved uptime, fewer fault-related escalations, and a clearer path to compliance in high‑load facilities. The top-feed, fusible configuration simplifies wiring and fault isolation in compact switchgear footprints, delivering safer installation and faster maintenance cycles for MCCs and distribution panels. The three-pole design delivers true three-phase protection, minimizing unbalanced loads and accidental single-phase exposure while ensuring reliable operation in 480V three‑phase networks. The electrical trip with a charge-before-close mechanism adds a controlled, safer switching sequence, reducing arcing and inrush events during maintenance or re-energization in crowded enclosures. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, and Auxiliary Contacts let you tailor protection and monitoring to your specific applications, helping you meet precise safety and regulatory requirements. Status indication via BFD with three normally-on lights provides immediate visibility of switch health, enabling proactive maintenance and faster fault diagnosis in real-time. Overall, the device supports robust protection in harsh environments, with durable enclosure compatibility and straightforward serviceability for long‑term reliability in industrial power distribution.

FAQs
CB1633T120480A is designed for top-feed, three-pole installation with fusible protection and a 16 in x 24 in x 28 in footprint. It supports 480V three‑phase systems and 120V control circuits, so plan for adequate enclosure space, wiring routes, and clearance for maintenance. Dimensions, weight, and mounting align with standard switchgear layouts, reducing retrofit complexity.
The CB1633T120480A delivers 1600A amperage with a 480V system voltage and 120V control voltage, along with NEMA ratings 1, 3R, 4, and 12. It uses fusible protection, top-fed configuration, and three-pole operation to safeguard three-phase motor feeders and power distribution panels in rugged environments.
The charge-before-close feature ensures the switch has a controlled, prepared state before closing, reducing arcing and inrush transients. This improves safety during energization, minimizes wear on contacts, and supports smoother handoffs in high‑demand switchgear installations, particularly during maintenance or reconfiguration of motor circuits.
Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contacts, Kirk Provisions, and status-related provisions enable customizable protection and monitoring. These options simplify regulatory compliance, enable early fault detection, and improve maintenance workflows by providing clear indicators and wiring flexibility for integrated safety schemes in industrial panels.
Warranty terms follow Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. Support includes UL Listed safety certification, documented specifications, and access to Eaton resources such as datasheets, catalog notes, and installation guidance to ensure reliable performance over the service life of the switch.
