The OMRON 3G3MX2-A4004-V1 is a compact micro drive from the MX2 series, sized for 0.4 kW motor loads on a 3-phase 400 VAC supply. It is a Type V1 variant, which typically denotes a specific firmware or feature set within the family. The panel-mounting design (IP10 or higher) means it goes inside a cabinet or closed wall-mount enclosure – not a standalone weatherproof unit.
The 0.4 kW output and 400 V class cover small induction motors – typical for conveyors, pumps, fans, or agitators in light industrial duty. The Type V1 designation tells you this is the V1 variant; confirm with the OMRON catalog if your application requires a specific I/O or fieldbus option (the MX2 series offers several control variants).
