The 3AXD50000940837: The 4 A normal-use current (In) drives a 1.5 kW motor at rated load. Light-overload current (IlD) is 3.8 A, also at 1.5 kW — the drive delivers full power without headroom for sustained overload; if your fan or pump cycle above 4 A, step up to the next frame. IE2 efficiency level meets the baseline for HVAC applications where premium efficiency isn't mandated. IP20 and NEMA Open Type mean it's for indoor, clean environments — no washdown or dust tolerance. Wall-mounting with the R1 frame fits a standard panel backplate; plan for clearance above and below for airflow.
