The CB2033B120600CSA offers a high amperage rating of up to 2000A and a voltage rating of 600V, enabling it to handle demanding motor control and power distribution tasks while maintaining safety and trip reliability in industrial environments. This feature translates to improved equipment protection, reduced downtime, and a clearer path to compliance in large switchgear and motor control centers. The 120V control voltage paired with a three-pole, three-wire configuration supports straightforward integration with existing control circuits and safety interlocks, delivering consistent operation across complex panels. Bottom feed, combined with a total footprint of 33 inches long, 25 inches wide, and 20 inches high, simplifies cabinet layout and wiring harness routing, reducing installation time and field labor costs. With a weight of 198 pounds, this unit provides secure mounting and vibration resistance, enhancing long-term reliability in challenging industrial conditions. Optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection extend protection coverage for critical lines, while Kirk Provisions and Auxiliary Contact Provisions offer flexibility for monitoring and signaling in heavy-duty applications. This combination supports easier retrofit projects and future-proofing for evolving safety standards in switchgear, panel boards, and distribution assemblies. Engineers often cite improved efficiency in maintenance planning due to the predictable trip behavior and clear diagnostics enabled by the CBC electrical trip profile, alongside compatibility with standard Eaton switchgear accessories and mounting schemes for rapid deployment in new builds or expansion projects.
