The ABB 3AXD50000956869 is an ACH180-04S-050A-4 LV AC micro drive built for HVAC duty, delivering 22 kW (50.0 A normal use) on a 380...480 V three-phase supply. Frame size R4, IP20 open-type enclosure, and BACnet onboard — this is a current-production unit, so no last-time-buy scramble.
Normal-use output is 22 kW / 50.0 A; heavy-duty use is 22 kW / 45.0 A; light-overload use is 22 kW / 48.0 A. UL ratings land at 30 Hp / 42.0 A across all duty classes. That means the drive is sized for a 22 kW motor on standard applications and still holds the same power when you need overload headroom — the current limit drops, but the kW rating stays flat. Efficiency is IE2, power factor 0.98, standby loss 38 W. Ambient temp max 60 °C, altitude 2000 m, IP20. Sound level 69 dB(A). The 4 digital inputs and 2 digital outputs plus 2 analog inputs and 1 analog output cover basic I/O for a fan or pump controller.
