FAQs
Plan for a top-feed, three-pole, three-wire arrangement with 208V system voltage and a 120V control circuit. The device weight and dimensions (16 in deep, 28 in high, 24 in wide) influence mounting clearance and access for maintenance. Ensure UL Listed compatibility and appropriate enclosure (NEMA 1/3R/4/12) to match environmental conditions.
The integrated control power transformer reduces external wiring and simplifies control circuit provisioning, while fusible protection provides fast, predictable interruption during faults. Together they improve safety margins, simplify preventive maintenance, and reduce fault‑domain downtime by shortening fault isolation times.
Yes. The unit is designed for 208V system voltage with a 120V control circuit, plus a 2000A amperage rating. Its three-pole, three-wire topology supports reliable protection coordination in large feeders and switchgear while maintaining compatiblity with standard control transformers.
The switch is UL Listed and compatible with multiple NEMA enclosure ratings (NEMA 1, 3R, 4, 12), supporting use in indoor, outdoor, and harsh environments. Optional features like Ground Fault Relay and Blown Fuse Detection offer enhanced protection within regulatory requirements for industrial power distribution.
The Eaton CB2033T120208G consolidates high‑current switching, control power transformation, and protective features in a single device, reducing wiring complexity and inventory. With UL Listing and robust enclosure compatibility, it enables safer installations, lower maintenance costs, and longer service life in critical distribution paths.
