Eaton CB1633T120480GRA9 Bolted Pressure Contact Switch - UL

High-capacity protection enables use in large motor feeders without upgrades to upstream switchgear. This switch is rated for 1600A and supports a 480V system, three-pole operation, and three-wire configuration. The result is reliable interrupt capability for demanding loads and consistent protection across the plant. The single-phase relay with capacitor trip device (SPVR) provides fast, controlled trips to minimize arc energy and protect critical equipment while keeping nuisance trips to a minimum in balanced loads and transient faults. Top-feed fuse configuration simplifies wiring within dense panel layouts, reducing installation time and material cost, and improving serviceability in retrofit projects. Ground fault protection with an integrated control transformer offers improved personnel safety and machine protection in wet or humid environments. UL Listed certification and NEMA enclosure compatibility ensure compliance and reliable performance in a range of industrial settings. Optional features, including ground fault relay, blown fuse detection, and auxiliary contact provisions, extend protection, diagnostics, and integration with centralized control schemes. The unit’s 16 x 24 x 28 inch footprint and 180 lb weight support careful planning in mechanical rooms and switchgear bays. Designed for compatibility with Eaton’s Switching Devices line, it streamlines procurement and warranty coverage while delivering long-term reliability in high-current, high-visibility protection applications.
