The ABB ACH531-01-046A-4 (3ABD00046362) is a low-voltage AC wall-mounted drive for HVAC applications, rated for 22 kW normal-use output at 46 A and 31.0 kVA apparent power. It runs on 380-480 V three-phase, 47.5-63 Hz, and is built into an R3 frame with IP20 protection. Standby loss is 16 W.
Mounts as a wall-mounted module (R3 frame). Input voltage range 380-480 V three-phase. Normal-use output is 46 A at 22 kW; light-overload rating is 42.8 A at 22 kW. IP20 enclosure. Ambient ceiling is 40 °C.
Efficiency class IE2 — meets the base level for variable-speed drives in most regions. Standby loss of 16 W is what it pulls when the motor is stopped but the control electronics stay live; factor that into panel heat budget if the drive idles for long periods.
