Product Information
Extended Description
3ABD00049857 ABB: The ACQ531-01 drives deliver innovative pump features for the water and wastewater industry, securing energy efficient flow of water and wastewater in your pumping solutions. This robust and compact wall-mounted drive has built-in simple pump application functionality. Usability is further enhanced with the optional intuitive Hand-Off-Auto control panel, the PC tool Drive composer and an optional Bluetooth=C2=AE control panel. The built-in energy calculator visualizes the energy savings achieved with the use of the drive. The ACQ531-01 variant comes in an IP20 enclosure as standard and can be installed on the wall.
Built-in pump application features streamline setup and optimize pump curves, reducing commissioning time and startup risk. By delivering tailored control logic for common pump scenarios, the drive translates complex hydraulics into predictable performance, improving energy efficiency and lifecycle reliability. This is particularly valuable in municipal water and wastewater networks where pump duty cycles vary and system uptime is critical. The result is smoother operations, lower energy bills, and a quicker path to regulatory compliance through proven pump management capabilities. The compact, wall-mounted design complements space-constrained pump rooms while minimizing wiring complexity and installation costs. This enables rapid retrofits in existing facilities without extensive panel upgrades, supporting a faster return on investment. Compatibility with Drive Composer and ABB accessories further enhances diagnostics, configuration, and long-term maintenance planning. For engineers, this means less custom programming and more standardized, repeatable deployments across multiple sites.
