High-current capability drives meaningful business impact. The CB1633B120480AX7 delivers 1600A capacity with a 2NO-2NC contact arrangement, enabling rapid isolation of large loads and reducing the need for downstream devices in switchgear. This translates to simpler protection logic and shorter downtime in heavy-duty panels. Applicable to three-pole, bottom-fed installations in equipment and process lines, it supports scalable protection as systems expand. Safety and reliability are enhanced by an electrical trip with charge-before-close, minimizing false trips and improving system stability in motor control centers and distribution panels. The device’s 480V system voltage and 120V control voltage enable flexible integration across industrial networks, while the NEMA 1, 3R, 4, and 12 ratings ensure robust performance in rugged environments. Optional features—Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, and auxiliary provisions—allow tailored protection without major rewiring, reducing lifecycle costs. The bottom-feed, fusible configuration simplifies wiring and maintenance, making replacements quicker and safer in field conditions. Overall, the unit offers a space-efficient, highly dependable solution for switchgear upgrades and panel modernization in manufacturing and infrastructure projects.
