Product Information
Extended Description
3AUA0000004193 ABB: ACS550-U1-07A5-2+B055
Soft-start and speed control extend motor life by reducing mechanical stress and electrical inrush, delivering a smoother process and less downtime in high-cycle conveyors. This translates to measurable energy savings and reduced maintenance costs in production lines that run continuously. The drive accepts a 208-240V supply with ±10% tolerance, enabling stable operation across minor voltage fluctuations common in aging facilities while avoiding costly re-wiring. IP54 protection coupled with a NEMA12 enclosure ensures dust and splash resistance in harsh factory floors, improving uptime in humid or dusty environments and simplifying compliance with plant hygiene expectations. Direct Connect and Bot/Side Conduit options simplify installation, reducing field wiring time and enabling quick cabinet mounting in tight spaces. The compact form factor supports retrofits and multi-drive banks in compact automation cabinets, optimizing floor space and installation costs. A robust diagnostic suite and built-in protection mechanisms address common objection items by enabling proactive maintenance and rapid fault isolation, improving overall line reliability. These capabilities align with long-term reliability goals for industrial customers deploying ABB drives across conveyors, pumps, fans, and light-process equipment while preserving compatibility with existing ABB accessories and service ecosystems.

FAQs
The ACS550-U1-07A5-2+B055 is designed for 208-240V systems and supports a 2HP motor drawing up to 7.5A. When installing, use the Dir Connect method for fast, secure wiring and choose Bot or Side Conduit termination to fit cabinet layouts. Ensure proper grounding and adherence to local electrical codes. This setup minimizes field wiring time and simplifies future maintenance.
Key performance specs include a 2HP (approximately 1.5 kW) output, 7.5A drive current, and a voltage tolerance of 208-240V ±10%. These factors govern starting torque, speed range, and control accuracy. The ACS550 supports soft-start and precise speed regulation, reducing mechanical wear on conveyors and pumps while delivering reliable operation in standard industrial loads.
Yes. The drive provides smooth start/stop, adjustable acceleration/deceleration, and torque control ideal for conveyors. Its IP54-NEMA12 enclosure ensures protection against dust and splashes in typical plant environments, while the compact footprint helps with cabinet space. Direct Connect and conduit options simplify mounting near conveyors, and built-in fault diagnostics help minimize downtime on critical lines.
The ACS550-U1-07A5-2+B055 features IP54 protection and a NEMA12 enclosure, offering rugged ingress protection for challenging environments. These ratings help ensure reliable operation in dusty or damp plant areas and support compliance with common industrial installation standards. Always verify regional electrical certifications (local CE/UL requirements) as part of your procurement process.
The drive can reduce energy consumption through efficient speed control and reduce equipment wear via soft-start and torque management, translating to lower maintenance costs and less downtime. Its diagnostic features enable proactive maintenance, reducing unexpected failures. In a typical light-industrial setup with conveyors or pumps, these factors collectively shorten payback periods and improve overall equipment effectiveness (OEE).
