The FRN75G1S-4C is a Fuji Electric FRENIC Series high-performance inverter rated for 75 kW motor output at three-phase 400 V supply. The G-type designation means it's configured for high-performance, multifunction duty — typically pumps, fans, conveyors, and other constant- or variable-torque loads that need closed-loop speed control. Enclosure is IP20, so this drive lives inside a clean panel or cabinet — not on the machine frame exposed to dust or washdown. The 75 kW rating positions it as a mid-to-large drive for production lines or building services where a single unit handles a substantial motor load.
Power stage and supply compatibility
Rated for three-phase 400 V input — standard European 400 V industrial mains, 50/60 Hz. The 75 kW output drives a motor of that nominal rating, so the BOM line for a 75 kW motor matches this inverter without oversizing. The FRENIC series is Fuji's general-purpose inverter line; the G-variant adds sensorless vector control and auto-tuning for induction motors, which matters when the load profile includes high starting torque or speed regulation within 0.5 %.
No stock-holding claim — each RFQ is handled against the real-time supply position.
Peer comparison — FRN7.5G1S-4C
The closest functional sibling is the FRN7.5G1S-4C, which is the same FRENIC G-series platform but rated for 7.5 kW motor output — ten times smaller. Both share the three-phase 400 V supply, IP20 enclosure, and G-type multifunction firmware.
