Part Number: 3AUA0000004200
Quick Summary
ABB ACS550 Drive is a variable frequency drive that controls AC motors for pumps and conveyors. Operators often struggle with energy waste from inefficient starts, motor trips, and misalignment between drive settings and load. Its IP54-NEMA12 protection and broad 48–63 Hz range help ensure reliable operation in dusty environments and diverse duty cycles. With easy DIR Connect wiring and conduit options, you gain faster installation, reduced wiring costs, and improved uptime, delivering tangible improvements in overall equipment effectiveness and energy performance.
Product Information
Extended Description
3AUA0000004200 ABB: ACS550-U1-031A-2+B055
Power rating and voltage compatibility align with standard US industrial motors: 10 HP at 208-240V ±10% with a 30.8 A draw. This setup enables precise speed control with minimal energy waste, translating to ongoing savings on running costs and reduced heat generation in motor-driven equipment. Applications include belt conveyors, pumps, and fans where variable speed control supports process optimization and longer motor life. Rugged IP54-NEMA12 enclosure provides dust and moisture protection, reducing downtime and maintenance scheduling while expanding reliable operation in harsh environments such as packaging lines and manufacturing floors. Bottom and side conduit options plus Direct Connect wiring simplify installation and permit flexible retrofits or new builds, cutting commissioning time and enabling safer, neater control panels. The 48–63 Hz range supports diverse duty cycles, improving compatibility with a wide range of motors and loads in automation projects. Compatibility with ABB automation ecosystems enhances scalability and reduces total cost of ownership over the system lifecycle.
