ABB 3AXD50000268979 Motors & Drives - IP21/IP55 Enclosures
Part Number: 3AXD50000268979
Quick Summary
ABB 3AXD50000268979 is an LV AC wall-mounted drive designed for water and wastewater pumping applications. Operators often battle energy waste, flow fluctuations, and equipment wear from inefficient pump control. This drive ships with UL listing and IP ratings—IP21 as standard, with IP55 variants available—to help ensure safe, compliant operation in challenging environments. By combining sensorless flow calculation, multipump control, level control, and a quick ramp approach with dry-run protection, it delivers measurable energy savings and reduced maintenance. The intuitive Hand-Off-Auto panel, Drive Composer PC tool, and optional Bluetooth control simplify commissioning, while built-in energy analytics supports lifecycle cost reductions for utilities and industrial water projects.

FAQs
The drive is designed for 575 V AC systems and supports currents up to 52 A, aligning with a 50 Hp rating. It is intended for wall mounting with IP21 protection by default, with IP55 variants available for harsher environments. When integrating with existing wiring, ensure proper shielding, compliant conduit, and a compatible circuit breaker spec to maintain NEMA/IEC alignment and to preserve safety clearances in the control panel.
Sensorless flow calculation estimates flow rates without a separate flow sensor, enabling precise speed control to match demand. Multipump control sequences multiple pumps efficiently, reducing start-stop cycles. Level control and quick ramps minimize pump cycling and hydraulic shock, while dry-run protection guards against motor damage when a pump runs dry. Together, these features reduce energy use and extend pump life in wastewater and water supply applications.
Yes. The ACQ580-based family integrated in this model provides pump-focused features ideal for lift stations, treatment facilities, and other municipal pumping schemes. The wall-mounted, compact design fits small pump rooms, while the built-in energy calculator supports ongoing optimization of head and flow to meet regulatory and service-level requirements.
The device carries UL listing for electrical safety and performance within its intended pumping applications. It also specifies IP21 enclosure protection by default, with optional IP55 variants for higher protection in exposed environments, helping you meet safety and installation standards in diverse market regions.
Regular maintenance is minimized by protection features like dry-run protection and soft-start ramps, reducing mechanical wear. The built-in energy calculator and energy analytics support ROI demonstrations during tendering by quantifying savings from reduced pump electricity use and extended pump life. Driver software updates via Drive Composer further enhance performance and longevity.
