ABB 3AXD50001002985 ACQ580-01 Drive, 18.5 kW, IP66

The 3AXD50001002985: Normal-use output is 18.5 kW / 38 A; heavy-duty use is 15 kW / 31.6 A. For a water pump running a steady load curve, the normal-use figure governs. For a lift station with periodic overloads, the heavy-duty rating is the one to spec against — it gives headroom without oversizing the frame. Enclosure is IP66 / NEMA 4X, so the drive is rated for washdown environments and outdoor installation without an extra cabinet. Ambient maximum is 40 °C — derate above that, but for most water/wastewater sites that's the standard operating range. Communication is CAN-based; no onboard Ethernet. If the site uses Modbus TCP or PROFINET, plan for an external gateway or a different drive variant. The 6 digital inputs and 3 digital outputs, plus 2 analog inputs and 2 analog outputs, cover typical pump control — start/stop, speed reference, feedback. Standby loss is 16 W — negligible for energy budgeting but worth noting if the drive is on a UPS-backed circuit. Power factor is 0.98, so line-side filtering is minimal.
