Selling Policy 25-000 - Distribution and Control Products and Services
50 A amperage rating with 600 Vac capability and a three-pole FG frame delivers targeted protection for engine-driven power systems in industrial facilities. Business impact: guards critical generator circuits against overloads while maintaining smooth operation during start-up transients, enabling safer panel installations and reduced downtime. Application: suits engine generator sets in manufacturing floors, data centers, and remote facilities, where reliability and predictable protection are essential. The fixed pickup and T186 trip type provide consistent response, minimizing nuisance trips in dynamic loading conditions. Application-specific advantage: engineers can rely on a known protection profile without recalibration after routine maintenance. The interrupt rating of 18 kAIC at 240 Vac and 14 kAIC at 480 Vac supports high fault current environments common in industrial generators, reducing equipment exposure to damaging faults. For integration, line/load terminals simplify wiring and field replacement, supporting quick swap-outs during maintenance windows. Certifications and standards—UL Listed, CSA Certified, IEC Rated—ensure compliance for global projects and OEM collaborations, reducing qualification steps. Weight and form factor (4 lb, compact F-frame) enable straightforward installation in control panels or generator enclosures. Warranty details follow Eaton policy, providing coverage through installation or shipment milestones. In practice, engineers experience improved maintenance cycles and lower total cost of ownership when pairing FG3050 with compatible engine-generator configurations under 60 Hz networks.
