ABB 3AXD50000430000 LV AC wall-mounted drive - THDi <3%
Part Number: 3AXD50000430000
Quick Summary
The ABB 3AXD50000430000 is an LV AC wall-mounted ultra-low harmonic drive for water and wastewater pumping. Operators struggle with harmonic distortion, energy waste, and unreliable pump protection in municipal and industrial projects. Key features include THDi under 3%, integrated low-harmonic filtering, and IP21 enclosure—with IP55 and flange options to match site requirements. By combining a compact wall-mount design with built-in pump application logic, it delivers energy efficiency, reduced maintenance, and faster return on investment for treated-water applications. Secondary benefits include sensorless flow calculation, quick ramps, and dry-run protection that minimize downtime and water hammer. This makes it a robust, field-ready solution for utilities and process plants seeking reliable performance.
Product Information
Extended Description
3AXD50000430000 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
This drive is designed for straightforward wall-mounted installation. It includes an active supply unit and integrated low harmonic filter, eliminating the need for external filters or transformers. Commissioning is supported by the Hand-Off-Auto panel and Drive Composer PC tool, with options for Bluetooth panels. It supports multipump and level control, plus quick ramps to minimize start-up transients.
The drive achieves THDi of less than 3%, substantially reducing harmonic distortion in the supply. This improves motor efficiency, reduces electrical stress on feeders, and helps meet power quality standards for municipal and industrial pumping. Its integrated low harmonic filter and compact design avoid the need for complex external harmonic mitigation.
Yes. The drive is purpose-built for water and wastewater applications, offering sensorless flow calculation, dry-run protection, and soft start/ramps that minimize water hammer. Its IP21 enclosure with optional IP55 mounting and flange options provides installation flexibility in pump houses and outdoor spaces, while its compact wall-mount footprint saves critical plant space.
The standard enclosure is IP21, suitable for indoor installations. Optional IP55 and flange mounting units are available to meet harsher environments or space constraints. Wall-mounted installation simplifies cabling and maintenance, and the option for flange mounting enhances compatibility with existing piping layouts and cabinet designs.
Built-in features such as an integrated low harmonic filter, dry-run protection, and sensorless control reduce maintenance needs and instrument count. Energy efficiency improvements lower operating costs, while easier commissioning and reduced preventive maintenance translate to faster ROI. Long-term reliability is supported by protected start routines and gentle ramping that minimize mechanical wear.
