Eaton Specification Sheet - CB3033T120480G7NF
Amperage rating of 3000A with non-fusible protection enables interruption of large three-phase loads without bulky fusing arrangements, reducing spare parts and simplifying heavy-current switching in MCCs and switchgear. This translates to faster commissioning, lower maintenance downtime, and safer disconnection in demanding electrical systems. System voltage of 480V with a 120V control voltage and a top-feed, three-pole, three-wire configuration simplifies wiring density and enables straightforward integration with standard control transformers and control circuits in industrial plants. The 2NO-2NC contact configuration provides flexible interlocking and multi-circuit control, supporting logic for interlocks, alarms, and redundant signaling in distribution panels and motor-control centers. UL Listed certification and NEMA compatibility (1, 3R, 4, 12) ensure compliance and reliable operation in varied environments, reducing compliance risk and installation rework. Optional features such as Ground Fault Relay, Blown Fuse Detection, and Single-Phase Protection extend fault-detection capabilities; Kirk Provisions and Auxiliary Contact Provisions further enhance control logic and expand retrofit opportunities. The switch’s substantial footprint (22.5 in L × 28 in H × 40 in W, 390 lb) requires deliberate planning but delivers rugged, secure mounting suitable for industrial enclosures and switchgear cabinets.

FAQs
Plan for top-feed wiring and the three-pole, three-wire configuration to ensure proper phase alignment. The unit’s 22.5 in length, 28 in height, and 40 in width require adequate enclosure space and mounting provisions. Use the ground fault and auxiliary options to tailor protection logic and minimize nuisance trips in dense switchgear environments.
A 3000A rating supports direct switching of large motor loads without relying on fuses, enabling simpler protection schemes and faster isolation during faults. This reduces spare parts, shortens downtime, and improves overall system reliability in motor-control centers and heavy-duty distribution panels.
Yes, the CB3033T120480G7NF is UL Listed, providing baseline safety certification for industrial installations. It supports NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 environments, enabling use in indoor and outdoor, dusty, damp, and harsher conditions when paired with appropriate enclosures.
Its 2NO-2NC contact configuration, top-feed design, and three-pole construction deliver flexible interlock options and robust control signaling. The non-fusible protection and 480V system compatibility simplify integration with MCCs and switchgear, while optional ground fault and auxiliary provisions enhance safety and diagnostic capabilities.
The non-fusible design reduces fuse replacements and associated maintenance, while the high current rating minimizes the need for frequent component changes. Reduced downtime during commissioning and fault diagnosis, coupled with UL/NEMA compatibility, translates to lower total cost of ownership and improved plant reliability.
