Eaton Specification Sheet - CB2533T120480GAX5
High-current capability and system versatility drive real business value. Feature → Business Impact → Application: The 2500A amperage rating handles large motor loads and feeders, reducing equipment staging and allowing a single protective device to govern critical paths in switchgear, MCCs, and distribution panels. This translates to lower overall components, simpler coordination, and measurable efficiency gains in continuity of service. Feature → Business Impact → Application: A 1NO-1NC contact configuration enables straightforward control logic and fail-safe interlocks, improving safety and reducing programming time during commissioning in industrial control panels and automated lines. Feature → Business Impact → Application: Top-feed, fusible configuration simplifies wiring and enhances fault isolation, cutting installation time and enabling cleaner panel layouts in compact switchgear assemblies. Feature → Business Impact → Application: Ground fault protection with a control power transformer provides enhanced personnel safety and selective tripping performance for critical processes in harsh environments. Feature → Business Impact → Application: Three-pole, three-wire design delivers true three-phase protection, streamlining integration into 480 V, 60 Hz power systems common in manufacturing, water treatment, and processing plants. Feature → Business Impact → Application: Electrical trip with charge-before-close minimizes arcing and ensures orderly shutoff sequences, supporting safer startup/shutdown in critical processes and reducing maintenance-induced outages. Grouping these features with UL Listed status and broad NEMA ratings (1, 3R, 4, 12) delivers compliance confidence and longer service life, while optional catalog notes offer Ground Fault Relay, Blown Fuse Detection, and auxiliary provisions to tailor protection to specific applications.
