The ABB 3AXD50000039030 is an ACQ580-01-039A-4 low-voltage AC wall-mounted drive, rated 18.5 kW normal-use output (38.0 A) on a 380...480 V three-phase supply. It is built for water and wastewater applications, with heavy-duty capability at 15 kW (31.6 A) and light-overload at 18.5 kW (36.1 A). The drive carries an IE2 efficiency level and is enclosed to IP21 / NEMA Type 1, frame size R3.
The normal-use current of 38.0 A is the continuous rating for sizing input cable and overload protection. Heavy-duty curve (31.6 A) applies for higher peak torque demands; light-overload (36.1 A) sits between the two. Standby loss is 16 W, which matters for panel heat budget in a sealed enclosure — that's the power the drive dissipates when the motor is stopped but the control electronics remain live. The 76 dB(A) sound level is typical for a fan-cooled drive of this frame; if the drive is going into a quiet zone (e.g., a treatment plant control room near operator stations), you may want to remote-mount it or add acoustic damping. The drive includes 2 analog inputs and 2 analog outputs, plus 6 digital inputs and 3 digital outputs — enough for a basic PID loop on a pump or fan, with a couple of status relays. Communication is via CAN; there is no onboard Industrial Ethernet interface, so if you need Modbus TCP or PROFINET, plan for an external gateway or a fieldbus adapter module.
Wall-mounted, frame R3. IP21 / NEMA Type 1 rating suits indoor installation without water spray or dust ingress. Maximum ambient temperature is 40 °C; altitude rating is 4000 m. The drive includes a control unit and a CR2032 lithium coin cell (220 mAh, 3 V) for backup of real-time clock and parameter memory — factor that into maintenance spares if the drive is in a remote location.
