Circuit Breakers Explained
Eaton Specification Sheet - FG3070
Three-pole FG frame molded case circuit breaker with fixed thermal and magnetic trips delivers 70A protection for engine-driven power units, rated for 600 Vac with interrupt capabilities of 18 kAIC at 240 Vac and 14 kAIC at 480 Vac. This combination provides reliable short-circuit and overload defense, minimizing engine-generator downtime and protecting downstream equipment in demanding 60 Hz environments. The FG3070 is designed for engine-generator panels with line/load terminals, enabling straightforward wiring and fast field installation, which reduces commissioning time and potential wiring errors. Generator ratings scale across voltages: 25 kVA/20 kW at 240 Vac, 51 kVA/40 kW at 480 Vac, and 63 kVA/51 kW at 600 Vac, ensuring correct protection across common generator sizes encountered in industrial facilities. Its compact footprint (7 in L x 5 in W x 6 in H) and modest weight of 4 lb simplify panel integration and retrofit projects. Certifications include UL Listed, UL 489 compatibility, IEC Rated, and CSA Certified, providing confidence for compliance audits and cross-border installations. The device supports engine-generator service with a fixed pickup (T186), offering predictable protection during startup and load transients while maintaining ease of procurement through standardized frame and terminals. Warranty coverage (one year from installation or 18 months from shipment) reduces risk for project owners and service teams, helping protect capital investments during deployment.
