Eaton Specification Sheet - CB2533T120480A9
Feature → Business Impact → Application: The three-pole top-feed design with a fusible top feed configuration enables high-current switching with streamlined wiring, reducing installation time and conductor complexity in large switchgear assemblies. This improves reliability and minimizes arc duration during trips, supporting safer, more predictable shutdowns in critical lines. Application: industrial power distribution centers and motor control centers that demand rapid, definitive protection at 480 V systems. Feature → Business Impact → Application: Amperage rating of 2500 A paired with a 120 V control voltage and a 480 V system voltage delivers a high-capacity protection solution for heavy equipment, enabling fewer components in series and reducing total installed cost while maintaining robust protection. Application: data centers, sheet metal, and metal fabrication plants with high current loads. Feature → Business Impact → Application: NEMA 1, NEMA 3R, NEMA 4, NEMA 12 compatibility broadens installation options and protects against dust, moisture, and corrosion in harsh environments. This translates to longer service intervals and lower maintenance overhead. Application: outdoor or damp indoor installations in process facilities. Feature → Business Impact → Application: Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contact Provisions, and Kirk provisions enable tailored protection schemes and rapid fault isolation, reducing fault-to-repair time and improving compliance with plant safety policies. Application: facilities pursuing enhanced fault-detection strategies and upgrade paths. Feature → Business Impact → Application: Three-wire, top-feed configuration with clear trip indication (BFD) improves visibility for operators during maintenance and testing, lowering misoperation risk and speeding commissioning. Application: commissioning and routine testing in industrial automation environments. Feature → Business Impact → Application: The combination of rugged construction, UL Listing, and Eaton support provides a predictable total cost of ownership with predictable maintenance intervals and reliable parts availability for long-term operational continuity.
