The ABB 3AXD50000750306 is an ACH531-01-09A5-4 LV AC wall-mounted drive for HVAC, rated 4 kW normal-use output at 9.4 A on a 380–480 V three-phase supply. Frame size R1 keeps it compact for panel mounting, and the IP20 enclosure suits indoor installation away from washdown areas.
Sizing and ratings
Normal-use output current is 9.4 A (Pn 4 kW), and the light-overload rating drops slightly to 8.9 A at the same 4 kW — the drive is sized for constant-torque HVAC loads like fans and pumps. The apparent power output of 6.5 kV·A gives you a rough transformer-sizing figure. Standby loss sits at 14 W, so the heat dissipated when the motor isn't running is low enough to ignore in most panel thermal calculations.
Installation notes
Mounts as an open-type module; the IP20 rating means it needs a clean, dry environment or an enclosure. Input frequency range is 47.5–63 Hz. Ambient temperature max is 40 °C.
