The ABB 3AXD50000039047 is an LV AC wall-mounted drive for water and wastewater, delivering 18.5 kW at 38.0 A in normal use, with a heavy-duty rating of 15 kW at 31.6 A. Input is 380-480 V three-phase, 47.5-63 Hz.
The drive carries two duty ratings: normal-use (Pn 18.5 kW, In 38.0 A) and heavy-duty (PhD 15 kW, IhD 31.6 A). The heavy-duty figure governs continuous operation for pumps with variable torque profiles or occasional overloads. Light-overload use (PlD 18.5 kW, IlD 36.1 A) sits between the two. Efficiency is IE2, with a power factor of 0.98 and standby loss of 16 W. Enclosure is IP55 with NEMA Type 12, rated for wall mounting in dusty or hose-down environments. Frame size R3. Ambient temperature max 40 °C, humidity 5-95% non-condensing, altitude up to 4000 m derated. Sound level 76 dB(A).
The drive includes 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs. Communication is CAN-based; no onboard Industrial Ethernet. A control unit is included. The lithium coin cell (CR2032, 220 mAh) backs the real-time clock.
