The 3AXD50000956852 is an ABB ACH180 micro drive built for HVAC fan and pump duty. Rated 22 kW normal use at 45.0 A on 380–480 V three-phase, with a heavy-duty curve at 18.5 kW and 38.0 A. Light-overload use matches the normal-use power at 22 kW but pulls 42.0 A — useful when the motor is oversized for the load profile. UL ratings land at 30 Hp normal, 25 Hp heavy-duty. Frame R4, IP20, open type. Communication is BACnet only — no industrial Ethernet onboard. That makes this a straight pick for building management systems (BMS) where BACnet MS/TP is the backbone. If the panel calls for Modbus TCP or PROFINET, this isn't the variant. The drive includes 2 analog inputs, 1 analog output, 4 digital inputs, and 2 digital outputs — enough for a basic VFD standalone or a simple BMS handshake.
Installation constraints
Rated for installation up to 2000 m altitude without derating. Ambient temperature max 60 °C — watch the panel cooling if the drive is in a tight enclosure. Standby loss is 38 W; that's the heat load when the drive is powered but the motor isn't running. Sound level 69 dB(A) — noticeable in a quiet mechanical room but typical for this power class. Power factor 0.98 at full load, which is good for harmonic compliance in HVAC applications.
