Quick Summary

Eaton FG3035 engine generator MCCB provides robust overcurrent protection for engine-powered power systems. Engineers and maintenance teams often struggle with protection devices that don’t coordinate with generator sets, leading nuisance trips and extended downtime. Certified to IEC rated, UL Listed, and CSA standards, it aligns with UL 489 and CSA requirements for safe, code-compliant operation. With fixed thermal and magnetic trips and a three-pole, 35 A, 600 Vac rating, the FG3035 delivers reliable coordination at 60 Hz. That combination translates to simpler installation, reduced warranty cost, and measurable uptime gains in critical applications such as standby power and engine-generator sets.

Feature: Fixed thermal and magnetic trips provide precise overload and short-circuit protection for engine-driven power systems. Business impact: Fewer nuisance trips and better generator coordination translate to higher uptime and lower maintenance costs. Application: Particularly effective in standby and prime power setups where reliable protection at 60 Hz and 600 Vac is critical for engine generator performance. The FG3035 is designed to handle typical generator starting transients, and its fixed pickup contributes to consistent protection across temperature and load conditions. In practice, technicians appreciate predictable tripping behavior that reduces run-to-trip variability. Feature: Three-pole FG frame with line and load terminals streamlines installation and panel integration. Business impact: Simplified wiring reduces commissioning time and potential misconnection, improving field reliability and enabling faster MTTR. Application: Ideal for engine-generator protection in compact control panels where space and wiring clarity matter. The design supports easy field wiring and consistent torque values; compatibility with standard conduit fittings keeps installation neat and compliant with best practices. Feature: 35 A amperage rating and 600 Vac voltage rating support generator sets up to 32 kVA/25 kW at 600 Vac; 18 kAIC at 240 Vac and 14 kAIC at 480 Vac, providing ample short-circuit margin. Business impact: Strong interrupt capability protects generator windings and improves fault isolation, lowering downtime, insurance risk, and potential equipment damage. Application: Suitable for industrial standby power and critical processes with high transient loads and backfeed considerations. Feature: Certifications include IEC Rated, UL Listed, and CSA Certified; UL 489 compliance reinforces conformance to safety requirements. Business impact: Code-compliance accelerates procurement and reduces engineering review time; auditors recognize the protection scheme as robust and traceable. Application: Across North America and international facilities, the FG3035 meets key safety and performance standards for engine-generator protection and power distribution equipment. Feature: Warranty and service terms—Eaton policy 25-000—one year from installation or 18 months from shipment; straightforward replacement and ongoing support. Business impact: Predictable coverage minimizes unexpected repair costs and simplifies vendor management, contributing to a faster ROI for generator installations. Application: Works with standard engine-generator protection schemes, maintenance schedules, and service contracts, ensuring reliable long-term operation.

FAQs

FG3035 uses a three-pole FG-frame design with line and load terminals, suitable for 60 Hz operation up to 600 Vac and a 35 A rating. Plan wiring to the line/load terminals, apply the manufacturer torque specs, and coordinate with the engine-start sequence and reverse protection. Mount in an appropriate enclosure to simplify service and future replacements.
The 18 kAIC rating at 240 Vac indicates the breaker can interrupt up to 18,000 amperes in a short-circuit at 240 Vac without damage, with 14 kAIC at 480 Vac. This provides ample margin for generator fault currents and windings. Proper coordination requires matching the generator rating and panel fault levels per Eaton datasheets.
Yes. With a 35 A at 600 Vac rating, 60 Hz operation, and engine-generator-specific features like fixed pickup and reverse protection, FG3035 supports both standby and prime protection. Its high interrupt capability and compatibility with up to 32 kVA/25 kW at 600 Vac make it reliable for critical loads and high transient conditions.
FG3035 carries IEC rated, UL Listed, and CSA Certified marks, including UL 489 compliance and CSA certification. This certifications mix supports NEC/CEC compliance, accelerates procurement, and eases audit processes for North American and international projects.
Maintenance is straightforward due to fixed trips and Eaton’s reliable design. The warranty follows Eaton policy 25-000—one year from installation or 18 months from shipment. The predictable protection reduces downtime and maintenance surprises, contributing to faster ROI for generator installations and easier long-term vendor support.
