22 kW at 400 V — what it drives
The FRN 2.2G1S-4C is a Fuji Electric Frenic-Mega Series inverter rated for 22 kW output on a three-phase 400 V supply. That power class covers a typical 30 HP motor — common on pumps, fans, and light conveyor drives in a 400 V industrial plant. The 'G' in the order code marks it as the high-performance, multifunction variant, meaning it handles sensorless vector control and V/f patterns for demanding load profiles, not just simple pump curves.
Enclosure and panel fit
The 'S' NEMA rating means a basic IP20/IP00 enclosure — no washdown protection, no sealed conduit entries. This drive mounts inside a clean, dry control cabinet where the panel itself provides the environmental seal. IP20 keeps fingers and tools out but does not block dust or moisture ingress. If the drive sits in a non-conditioned area, the cabinet needs a filtered vent or a cooling fan to keep the internals within the operating temperature range.
For a BOM line that needs a 22 kW, 400 V Fuji drive, this is the direct order-code match.
