Drive for HVAC duty, wall-mount, IP66
The ABB 3AXD50001002794 is a wall-mounted drive rated 22 kW normal use at 45 A on 380-415 V three-phase. The IP66 and NEMA 4X enclosure handles washdown environments without a separate cabinet. Built-in BACnet gives the BMS direct access to drive parameters without an external gateway. The 2 analog inputs and 2 analog outputs are there for duct static pressure or temperature feedback loops.
Sizing and overload choices
The drive carries three duty ratings. Normal use: 22 kW, 45 A. Heavy-duty: 18.5 kW, 37.7 A. Light-overload: 22 kW, 42.8 A. The UL light-overload rating is 30 Hp, 44 A. Standby loss is 16 W — the drive idles cool, which matters when the panel ambient is already near 40 °C.
Wall-mounted, frame size R3. The IP66 and NEMA 4X rating means no rain hood or drip shield needed outdoors. The 40 °C ambient limit is the operating ceiling.
