Part Number: 3AXD50000429950
Quick Summary
ABB 3AXD50000429950 LV AC drive delivers ultra-low harmonic control for water and wastewater pumping applications. Operators often struggle with harmonic distortion, energy waste, and the logistical burden of external filters or complex multi-pulse arrangements. This drive is CE-marked and designed with an IP21 enclosure as standard, with IP55 and flange-mount variants available for harsher environments, delivering reliable performance in challenging facilities. Built-in pump application features such as sensorless flow calculation, multipump control, level control, and dry-run protection help protect pumps and optimize operations. The included Hand-Off-Auto control panel, Drive Composer PC tool, and optional Bluetooth panel streamline commissioning, while the compact wall-mounted design supports easy retrofits and reduced installation costs. This combination drives tangible business value through efficiency and reliability.
Product Information
Extended Description
3AXD50000429950 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
ABB 3AXD50000429950 is a wall-mounted LV AC drive with an integrated low harmonic filter and supply unit, eliminating external filters. Wiring typically follows standard three-phase motor and control circuit practices, with connections to the HOA switch, motor terminals, and control interfaces via Drive Composer or Bluetooth panel. The IP21 enclosure is straightforward to mount, with IP55 and flange options available.
THDi <3% indicates very low harmonic distortion currents drawn by the drive, improving power quality and reducing stress on electrical infrastructure. This helps meet utility and equipment standards for harmonic emissions, supports energy efficiency goals, and simplifies compliance in municipal and industrial pump installations where clean power is essential.
Yes. The ABB 3AXD50000429950 is designed for water and wastewater pumping, offering sensorless flow calculation, multipump control, level control, dry-run protection, and quick ramps. Its compact wall-mounted form, built-in filter, and pump-focused features optimize flow, protect pumps, and reduce downtime, making it well-suited for municipal treatment plants and pumping stations.
The drive is CE-marked and ships with an IP21 enclosure as standard. For harsher environments, IP55 enclosure variants and flange-mount options are available. These options support installation in outdoor or challenging plant areas while maintaining safe device operation and compliance with common electrical standards.
The integrated low harmonic filter, reduced external components, and sensorless pump intelligence lower installation and maintenance costs while improving energy efficiency and pump reliability. By stabilizing motor operation, enabling longer pump life, and reducing downtime, facilities can achieve a favorable ROI through energy savings and lower BOM/maintenance overheads.
