The Fuji Electric FRN0044E2S-4C is a FRENIC Series high performance inverter rated for three-phase 400V input and 44A output, housed in a basic enclosure (IP20/IP00). The 'S' enclosure code means this unit ships without an integrated IP54/NEMA 12 protection — it's designed for cabinet mounting where the panel provides the environmental seal.
The 44A rating on a three-phase 400V supply positions this drive for motor loads roughly in the 22–30 kW range, depending on the motor's full-load current and duty cycle. The IP20/IP00 enclosure means the drive must be installed inside a panel with its own environmental rating — it's not a standalone unit for washdown or outdoor use.
