The ABB 3AXD50000038998 is a wall-mounted HVAC drive rated 0.75 kW normal-use power (Pn) at 2.6 A output current (In) on a 380–480 V three-phase supply. It ships with the control unit included. The drive is built for HVAC duty — BACnet communication is standard, and the IP55 / NEMA Type 12 enclosure handles the dust and condensation you find in mechanical rooms or rooftop units. Standby loss sits at 14 W, and full-load power consumption is 44 W.
The normal-use rating (Pn 0.75 kW, In 2.6 A) covers your typical fan or pump with a quadratic torque curve. If the application is heavy-duty — say a positive-displacement pump or a conveyor start — the drive still delivers 0.6 kW (PhD) at 1.8 A (IhD). Light-overload use, which is essentially the same as normal use for this frame, is rated 0.75 kW (PlD) at 2.5 A (IlD). Under UL listing, the light-overload output is 1 Hp at 2.1 A, and heavy-duty UL current is 1.6 A. So if you're spec'ing for a North American 1 Hp motor on a light load, this drive fits; for a full 1 Hp heavy-duty cycle, check the 1.6 A UL limit against your motor FLA. The drive has 2 analog inputs and 2 analog outputs — enough for a speed reference from a BMS or a pressure transducer plus a feedback loop. Digital I/O is 6 inputs and 3 outputs, which covers start/stop, fault reset, and a run status relay without adding an expansion module. There is no onboard industrial Ethernet port; BACnet is the only fieldbus protocol listed, so if you need Modbus TCP or PROFINET, you'll need a separate gateway or a different drive variant.
Wall-mounted, frame R1. The IP55 / NEMA 12 rating means it's suitable for indoor locations where you might get hose-down or condensation — think HVAC plant rooms, not a clean dry cabinet. Maximum ambient temperature is 40 °C, and operating humidity can go to 95% non-condensing. The enclosure is Type 12, so it's dust-tight and drip-proof, but it's not rated for outdoor direct rain or submersion.
