The ABB ACH480-04-046A-4 (3AXD50000275748) is a 22 kW normal-use HVAC drive module on 380–480 V three-phase, rated 45 A in normal duty. Heavy-duty use drops to 18.5 kW and 38 A; light-overload use holds at 22 kW but current limits to 42.8 A. UL ratings are slightly lower — 40 A normal, 34 A heavy-duty — so if the job carries a UL stamp, size against those numbers. Frame size R4, IP20 open type, max ambient 50 °C. Standby loss is 38 W; full-load power consumption hits 582 W. Sound level 69 dB(A) — noticeable in a quiet mechanical room but normal for this class. Built-in BACnet communication, no industrial Ethernet port. Two analog inputs, two analog outputs, six digital inputs, three digital outputs. Includes the control unit; the lithium coin cell (CR2032, 220 mAh) keeps the real-time clock alive.
WEEE category 5 (small equipment, no dimension over 50 cm). Efficiency class IE2. Frequency range 47.5–63 Hz.
