The ABB 3AXD50001063122 is a wall-mounted HVAC drive rated 45 kW normal-duty output at 89 A, with a heavy-duty rating of 37 kW at 72 A for tougher load profiles. It runs on three-phase 380-480 V input and delivers 62 kV·A apparent power. The IP21 enclosure with NEMA Type 1 rating means it's suited for indoor installation in electrical rooms or mechanical penthouse spaces where drips and falling dirt are present, but not washdown environments. Wall-mount it in the standard vertical orientation; frame size R4 keeps the footprint manageable for retrofit into existing panel layouts. On the control side you get 2 analog inputs, 2 analog outputs, 6 digital inputs, and 3 digital outputs — enough for a basic PID loop with feedback and start/stop interlock. The onboard BACnet communication protocol means it talks directly to building management systems without an external gateway; no Industrial Ethernet port here, so the BACnet MS/TP channel is your primary fieldbus link.
Three duty ratings are listed: normal-use (Pn 45 kW, 89 A), heavy-duty (37 kW, 72 A), and light-overload (45 kW, 83 A). For a variable-torque HVAC fan or centrifugal pump, the normal-use 89 A rating is the one you spec to — it matches the ACH580-01-089A-4 catalog entry. The light-overload 83 A curve sits between them; use it when the load profile is mostly normal but sees occasional short-duration peaks. Standby loss is 21 W — the drive's control electronics and cooling fan draw that when the motor is stopped but the drive is powered. Full-load power consumption hits 1028 W at rated output, so factor that into your enclosure cooling calc.
Installation constraints and environment
Ambient temperature max is 40 °C — derate output current above that. The altitude rating of 4000 m means it runs at full rating up to 4000 m. Sound level is 70 dB(A) at full fan speed. Frequency range is 47.5 to 63 Hz, covering 50 Hz and 60 Hz grids. The onboard lithium coin cell (CR2032, 220 mAh) keeps the real-time clock and parameter backup alive during power-downs — expect about 5-7 years of retention life at 40 °C ambient.
