The ABB 3AXD50000039038 is a wall-mounted drive rated for 5.5 kW normal use (12.6 A) on a 380-480 V three-phase supply. Heavy-duty use is rated at 4 kW (9.4 A), and light-overload use at 5.5 kW (12.0 A).
The 12.6 A normal-use current is the figure to size branch protection and cabling for continuous motor duty. Heavy-duty current of 9.4 A applies when the drive is paired with a motor one frame size larger or for constant-torque loads like conveyors. The 0.98 power factor holds across the load range, so upstream transformer and generator sizing can be tighter than with older drives. Standby loss of 14 W matters for panels with limited ventilation or where the drive idles for long periods.
Integration notes
Wall-mounted with IP55 and NEMA Type 12, this drive is intended for direct installation on a machine frame or wall bracket, not a sealed cabinet. The 2 analog inputs and 2 analog outputs support 4-20 mA transducer feedback for pump control. Digital I/O count is 6 inputs and 3 outputs, enough for start/stop, fault reset, and a run status relay. Communication is CAN-based; there are no industrial Ethernet interfaces on this variant, so a separate gateway or fieldbus adapter is needed for Ethernet integration. The control unit is included. Ambient temperature is limited to 40 °C maximum; derate above that. Operating humidity range is 5 to 95% non-condensing. Altitude rating is 4000 m, which covers most high-altitude installations without derating.
