Eaton CB2533B120480KG bolted pressure switch UL Listed

The CB2533B120480KG provides a high current solution with a 2500 A amperage rating at a 480 V system and a 120 V control circuit, enabling efficient protection for large motor feeders and distribution panels in harsh industrial environments. By consolidating switching and protection into a single three-pole device, it reduces panel complexity, speeds fault isolation, lowers wiring errors during installation, and simplifies future upgrades. This bottom-feed, three-wire configuration is particularly well-suited for facilities that demand fast, reliable tripping, predictable coordination with upstream protective devices, and minimal downtime during routine maintenance. Interlock functionality and fusible protection add critical safety margins during startup and servicing, helping prevent accidental re-energization and streamlining lockout-tagout procedures across multiple bays. The ground fault integration with a control power transformer simplifies fault detection, improves coordination across feeders, and supports quick fault location without extensive disassembly. Designers benefit from fewer components to source, reduced failure points, and a more compact protection footprint that fits standard switchgear envelopes while maintaining compliance. UL Listed certification underpins compliance with essential electrical safety standards, while the unit’s NEMA ratings—1, 3R, 4, and 12—define enclosure protection suitable for dusty, damp, and harsh industrial environments. These certifications translate into robust reliability in manufacturing, mining, and process facilities where uptime is mission-critical, and the documentation supports regulatory audits and quality programs. Catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, Auxiliary Contact Provisions, and other configurations are available, enabling tailored protection schemes without adding separate modules. This flexibility reduces installation time, accelerates commissioning, and improves spare parts planning by standardizing on a single, versatile protection platform across multiple lines. The result is a safer, more compliant panel that aligns with global electrical codes while delivering consistent performance across a diversified plant footprint. Overall, the CB2533B120480KG delivers reliable, code-compliant protection with straightforward installation in bottom-feed, three-pole configurations that minimize field adjustments after commissioning. Operators gain safer start-up, easier maintenance, and predictable life-cycle costs, improving asset availability, uptime, and total cost of ownership in critical electrical infrastructure. For engineers designing switchgear and motor control centers, this Eaton solution offers a proven balance of performance, safety, and installability that supports fast project execution and long-term reliability.
