ABB 3AXD50000428748 LV AC wall-mounted drive - THDi <3%
Part Number: 3AXD50000428748
Quick Summary
ABB 3AXD50000428748 LV AC wall-mounted ultra-low harmonic drive is designed to optimize pumping in water and wastewater applications. It helps minimize harmonic distortion and simplifies installation in compact spaces, addressing common pain points around filter banks and power quality. The solution carries UL-listed protection and IP21 enclosure, with IP55 and flange options for robust environments, and supports integrated features that boost reliability. Secondary benefits include sensorless flow calculation, level control, and dry-run protection, contributing to energy efficiency and reduced total cost of ownership. For engineers and plant managers, the result is easier commissioning, fewer parts to stock, and predictable pump performance across varying duty cycles.
Product Information
Extended Description
3AXD50000428748 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 low harmonic performance reduces harmonic distortion and eliminates the need for external filters, cutting installation time and panel space while improving power quality for municipal pumping stations. Businesses see lower energy waste and smoother motor current, which translates to longer motor life and easier compliance with grid standards in water and wastewater facilities. The unit’s ultra-low THDi (<3%) supports sensitive electrical environments and reduces electromagnetic interference with nearby equipment, enabling quieter operation and fewer interference complaints. Built-in pump application features—sensorless flow calculation, level control, dry-run protection, quick ramps, and soft pipe fill—minimize pump wear, prevent dry runs, and shorten commissioning time during startup or capacity changes. Compatibility with the Hand-Off-Auto control, Drive Composer PC tool, and optional Bluetooth control panel simplifies remote monitoring and field service, supporting faster repairs and reduced maintenance costs. The compact wall-mounted form factor with standard IP21 and optional IP55 flange configurations enables easier retrofits and more flexible installation in constrained plant spaces, delivering measurable improvements in uptime and total cost of ownership.

FAQs
When retrofitting, plan for a compact footprint with the IP21 enclosure as standard and assess potential IP55 flange options for harsher environments. Ensure correct cable routing to the motor and power supply, confirm compatible motor ratings, and harness the integrated features such as soft ramps and dry-run protection to minimize startup shocks and pump wear. Use the Drive Composer tool to streamline commissioning and validation.
The drive delivers Pn 7.5 kW with 17.0 A at 400 V in typical configurations, and UL listing corresponds to Pld 10 Hp at 14.0 A and 480 V. It achieves THDi < 3%, and comes with an integrated low harmonic line filter, reducing the need for external components and simplifying electrical design for pumping systems.
Yes. The drive includes pump-specific features such as sensorless flow calculation, level control, dry-run protection, quick ramps, and soft pipe fill, which improve pump reliability and control. Its compact wall-mounted design and integrated filter are especially advantageous for confined plant spaces typical of water/wastewater installations.
The product is UL-listed for motor protection and control in pumping applications, with an IP21 standard enclosure and options for IP55 and flange mounting to suit harsher environments. These certifications and ratings support compliance with electrical safety and industry guidelines in municipal and industrial water facilities.
ROI improves through energy efficiency gains from ultra-low harmonic operation, reduced maintenance due to integrated filters and protection features, and faster commissioning via Drive Composer and optional Bluetooth interfaces. Fewer external components mean lower capital expenditure, simpler spare parts management, and shorter downtime during pump system upgrades.
