Product Information
Extended Description
3AXD50000428977 ABB: The ACQ580-31 drives deliver innovative pump features for the water and wastewater industry, securing energy efficient flow of water and wastewater in your pumping solutions. The ultra-low harmonic variant provides ultimate harmonic performance, reaching even less than 3 % THDi, and exceeding the requirements set by low harmonic standards and recommendations. The drive includes an active supply unit and integrated low harmonic line filter, meaning there is no need for external filters, multi-pulse arrangements or special transformers.
Other features include output voltage boost and power factor correction. This robust and compact wall-mounted drive has built-in pump application functionality such as sensorless flow calculation, multipump control, level control, soft pipe fill, dry run protection, quick ramps and a solution for keeping the impeller of the pump clean. Usability is further enhanced with the intuitive Hand-Off-Auto control panel, the PC tool Drive composer and an optional Bluetooth=C2=AE control panel. The ultra-low harmonic wall-mounted variant comes in IP21 enclosure as standard. Also, IP55 and flange mounting units are available.

FAQs
The ABB 3AXD50000428977 is designed as a wall-mounted LV AC drive with ultra-low harmonic performance (THDi <3%), built-in low harmonic filtration, and integrated pump-specific features like sensorless flow calculation and dry run protection. This combination reduces electrical disturbances, enhances reliability in water and wastewater networks, and supports energy-efficient, stable pumping operations in municipal and industrial settings.
Installation is streamlined by the integrated active supply unit and low harmonic line filter, which minimizes external components. The device is standard IP21 and available in IP55 variants, allowing placement in plant rooms or harsher environments. Wiring follows common VFD practices for 480 V systems, with Hand-Off-Auto control as a user interface option and Drive Composer for configuration.
Key specs include 40 Hp output, 52 A current, 480 V supply, THDi < 3% for ultra-low harmonic performance, and a compact wall-mounted form factor. It includes an integrated low harmonic filter, voltage boosting, and power factor correction. Compatibility with sensors and multi-pump configurations makes it well-suited for municipal and industrial pumping applications.
Water utilities, wastewater treatment plants, and process industries with critical pumping requirements benefit the most. The ultra-low harmonic design minimizes electrical stress on transformers and switchgear, improves energy efficiency, and supports compliant power quality in distribution networks, especially where multiple pumps operate in parallel or across long intake and discharge lines.
ROI is driven by energy savings from improved power factor and reduced harmonic losses, plus lower maintenance due to dry run protection and sensorless control. The integrated features reduce the need for external filters and complex configurations, cutting installation time and spare-parts inventory. Overall, the drive lowers total cost of ownership in water and wastewater pumping applications.
