Eaton Specification Sheet - CB3033T120480KG14
Amperage rating of 3000A provides capacity for large loads, delivering reliable protection in high-demand applications and reducing the risk of nuisance trips. This translates to measurable business impact: improved uptime, lower maintenance costs, and safer motor control centers. The three-pole, 3 NO-3 NC contact configuration enables flexible control schemes, simplifying wiring and enabling safe start/stop sequences in demanding process lines and packaging machinery. In practice, the top feed and fusible protection simplify installation, minimize space requirements, and improve protection against short circuits, which reduces the need for frequent component replacements in harsh plant environments. Ground fault functionality, along with optional Ground Fault Relay and auxiliary provisions, enhances safety compliance for installations near personnel and critical infrastructure, reducing liability and potential downtime. The rugged enclosure and NEMA compatibility support operation in dusty or damp environments typical of manufacturing floors, increasing service intervals and lowering total cost of ownership. Optional features like Blown Fuse Detection and Single Phase Protection address common failure modes, enabling proactive maintenance and reliability. Customer deployments often report faster installation, easier panel integration, and a clearer path to compliance with electrical safety standards. This model’s warranty and Eaton support network provide additional peace of mind for long-term capital projects.

FAQs
When installing the CB3033T120480KG14, plan for top-feed wiring, 3-wire connections, and proper grounding. Ensure the control voltage (120 V) wiring is segregated from the 480 V power circuits and that the panel provides adequate clearance for the three-pole assembly. Use the optional ground fault protections if your application requires enhanced fault sensing and consult the Eaton specification sheet for torque values and wiring schematics.
Yes. The device is designed for 480 V system voltage with a 120 V control circuit, supporting high-current operation up to 3000 A. Its 3 NO-3 NC configuration enables flexible control logic, and the fusible protection provides coordinated protection with upstream fusing. Verify panel ratings and ensure wiring methods meet local electrical codes before deployment.
Key features include the interlock option, 3 NO-3 NC contact configuration, and fusible protection that work together to prevent unsafe energization. Ground fault capability and auxiliary provisions enhance safety and diagnostics, while the top-feed design simplifies installation in crowded switchgear. These elements support safer maintenance, reduced risk of arc flash, and compliant operation in high-energy environments.
The CB3033T120480KG14 is UL Listed and carries NEMA ratings for 1, 3R, 4, and 12 enclosures. These certifications indicate safety and suitability for a broad range of indoor and outdoor industrial applications, including damp or dusty environments. Optional features such as ground fault protection and fuse protection further align the product with industry safety standards and risk management requirements.
Maintenance benefits arise from its rugged build, fusible protection, and optional fault-detection features, which reduce unplanned outages. The unit’s warranty (one year from installation or 18 months from shipment) and Eaton support network help control lifecycle costs. ROI is typically driven by minimized downtime, extended mean time between failures, and safer, more reliable interlock protections in critical power-distribution applications.
