The Fuji Electric FRN0.4G1S-4C is a FRENIC Series high performance inverter rated for a 0.4 kW motor on a three-phase 400V supply. This is the entry-level power point in the FRENIC family, sized for small pumps, fans, and conveyor drives where you need V/Hz or vector control without oversizing the cabinet.
The 0.4 kW nominal applied motor rating means this drive is a direct match for a standard 0.4 kW (0.5 HP) four-pole induction motor on a 400 V line. The three-phase 400 V input is common across European and Asian industrial panels — no transformer needed if your plant runs 380-415 V. Enclosure is Standard (IP20/IP00), so it's protected against finger contact (IP20) on the electronics but the power terminals are open (IP00) and need to live inside a panel or an additional enclosure.
