ABB 3AXD50000428991 LV AC drive - ultra-low harmonic
Part Number: 3AXD50000428991
Quick Summary
ABB 3AXD50000428991 LV AC drive is a compact, wall-mounted controller that delivers ultra-low harmonic performance for water and wastewater pumping. Engineers face harmonics, energy waste, and integration complexity; this drive minimizes THDi while streamlining installation with an integrated low harmonic line filter and a built-in supply unit. It carries UL listing and CE compliance, with an IP21 enclosure as standard and optional IP55 or flange-mount variants for tougher environments. The drive also includes pump-specific features such as sensorless flow calculation, multipump control, level control, and dry run protection, all accessible via Hand-Off-Auto panels and Drive Composer. By combining robust protection with ease of use, it helps operators reduce energy costs and downtime across municipal and industrial pumping systems.
Product Information
Extended Description
3AXD50000428991 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.
Integrated ultra-low harmonic design reduces THDi to well below 3%, lowering transformer and cabling stress while improving overall power quality. This directly translates to smaller filter requirements, fewer maintenance events, and improved motor efficiency for water pumping applications. The business impact is tangible: lower energy bills, reduced capacitor banks, and simpler compliance with harmonic standards in municipal and industrial plants. The drive’s built-in active supply unit and integrated low harmonic line filter eliminate the need for external filters or complex multi-pulse arrangements, accelerating installation and reducing BOM costs for water treatment and wastewater facilities. In terms of application, this supports reliable operation of pumps in lift stations, aeration basins, and process loops, with measurable improvements in uptime and grid compliance. Compatibility with 480 V systems, 60 HP and 77 A ratings ensures straightforward replacement in existing pump farms, while compact wall-mounting saves panel space and simplifies retrofits.

FAQs
This drive is designed for 480 V systems with a 60 HP / 77 A rating and comes wall-mounted with an IP21 enclosure (IP55 optional). Its integrated low harmonic filter and active supply unit simplify retrofits by eliminating external filters and transformers, making it straightforward to upgrade existing pump stations while preserving current piping and wiring layouts.
The ultra-low harmonic variant is engineered to achieve THDi well below 3%, significantly reducing grid and motor stress. This improves power quality, reduces EMI concerns, and supports compliance with low-harmonics guidelines, which is critical for sensitive utility networks and multi-pump installations.
Yes. The drive offers multipump control and level control features, along with sensorless flow calculation and dry run protection. These capabilities enable coordinated pumping strategies, improved redundancy, and efficient sequencing, reducing wear on pumps and enabling smooth operation in basins, digesters, and equalization tanks.
This drive is UL-listed and CE-compliant, with standard IP21 splash-protected enclosure and options for IP55 flange-mount variants. These certifications and ratings help meet regulatory requirements and environmental demands in municipal and industrial facilities, while providing robust protection for outdoor or harsher indoor environments.
The integrated design reduces external components, lowers BOM costs, and shortens commissioning time with Drive Composer and Hand-Off-Auto control. Energy efficiency improvements from harmonic reduction and optimized pump operation translate to lower lifecycle costs, longer pump life, and faster payback in water treatment and wastewater pumping applications.
