ABB 3AXD50000429998 AC Drive - Ultra-low harmonic THDi <3%
Part Number: 3AXD50000429998
Quick Summary
ABB 3AXD50000429998 AC Drive delivers ultra-low harmonic control for water and wastewater pumping systems. High harmonic distortion can shorten pump life, waste energy, and complicate regulatory compliance. This drive supports CE marking and standard IP21 enclosures, with IP55 and flange-mount options available to match plant layouts. By combining an integrated low-harmonic filter with a built-in supply unit, it eliminates the need for external filters or complex transformer arrangements. The Hand-Off-Auto control panel, Drive Composer PC tool, and optional Bluetooth panel simplify commissioning and startup, helping maintenance teams reduce downtime and capitalise on energy savings across your pumping infrastructure. This combination supports safer, compliant operations.
Product Information
Extended Description
3AXD50000429998 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 3AXD50000429998 is a wall-mounted LV drive with an integrated low-harmonic filter and built-in supply unit, reducing external hardware needs. It supports Hand-Off-Auto operation, Drive Composer for commissioning, and is compatible with standard ABB motor configurations used in water and wastewater pumping stations.
The ultra-low harmonic variant delivers THDi below 3%, minimizing harmonic distortion, protecting pumps from premature wear, and enabling simpler compliance with low-harmonic standards. The integrated filter means no external filters or multi-pulse systems are required, saving space and costs.
The drive comes with CE marking for European compliance and standard IP21 enclosure protection. IP55 mounting options and flange-mount variants are available to suit harsher environments and tighter plant layouts.
Sensorless flow calculation enables precise flow control without external sensors, while multipump control coordinates multiple pumps for stable pressure and energy savings. These features yield smoother operation, reduced cycling, and better process stability in treatment plants.
With an integrated filter and protection features like dry run protection and quick ramps, maintenance burdens are reduced and pump wear is minimized. Drive Composer support accelerates commissioning, shortening downtime and delivering faster payback in municipal or industrial pumping projects.
