Product Information
Extended Description
3AUA0000005381 ABB: ACS550-U1-180A-4+B055
IP54-NEMA12 rugged enclosure protects the drive from dust and moisture. This protection reduces unplanned downtime and maintenance costs, enabling reliable operation in harsh plant areas. Applications include conveyors, pumps, and fans operating in dirty or humid environments. The 150HP and 180A rating provides robust motor control for mid-size loads, delivering consistent speed and torque with fewer trips and improved process stability in manufacturing lines. This translates to lower energy waste and improved throughput on equipment such as material handlers and process pumps. The 380-500V ±10% voltage range and 48-63Hz frequency tolerance enable global deployment without regional rewiring, simplifying procurement and reducing spare parts inventory. Users can confidently run multi-national projects with a single drive platform across plants in different countries. Dir Connect wiring and bottom/side conduit simplify panel installation, cutting commissioning time and minimizing wiring errors for faster project startup. With efficient fault handling and scalable control, ABB ACS550 drives contribute to energy savings and long-term operational ROI on conveyors and automated lines.
