ABB ACS255-03U-10A5-2+B068 LV AC Micro Drive - IP66/NEMA 4X
Part Number: 3AUA0000234205
Quick Summary
ACS255 LV AC micro drive provides precise speed control for washdown-ready machines in augers, mixers, pumps, fans, and conveyors. That means less downtime, simpler wiring, and faster commissioning for OEMs and maintenance teams. The drive is UL (NEMA 4X) and IP66 rated, built for corrosion resistance in washdown environments. With embedded Modbus-RTU, sensorless vector control, and V/Hz profiles, it integrates easily with PLCs and HMI systems, delivering efficient motor control and predictable performance. Manufacturers benefit from extended service life, energy savings, and easier replacement through a common ABB drive family. Designers appreciate the compact footprint, integrated keypad, and straightforward parameterization that reduces commissioning time.
Product Information
Extended Description
3AUA0000234205 ABB: The ACS255 drive comes in several variants ensuring seamless integration into machines. The UL (NEMA) TYPE 4X / IP66 ACS255 is constructed with corrosion resistant materials for durability and increased survival in wet, dirty, or washdown applications indoors or outdoors. Common application includes augers, mixers, pumps, fans and conveyors. The key features include an integrated keypad for easy configuration, precise process control with V/Hz control and sensorless vector control for both AC induction and PM motors, enhanced short circuit protection, operating mode selection with variable torque and constant torque V/Hz profiles, and embedded Modbus-RTU communication interface for real time control and monitoring.
IP66 / UL Type 4X-rated housing provides robust protection against washdown and corrosion, extending service life in harsh environments while reducing maintenance costs and downtime. This maturity translates to higher machine availability in food and beverage, chemical processing, and water treatment applications where exposure to moisture and cleaning agents is routine. Integrated keypad simplifies configuration, enabling quicker commissioning and fewer wiring errors, which lowers engineering labor and project risk. Sensorless vector control supports both induction and PM motors, delivering precise torque and smooth acceleration, improving process stability for pumps, mixers, and conveyors. V/Hz control with variable and constant torque profiles optimizes performance across load ranges, cutting energy consumption and extending motor life. The embedded Modbus-RTU interface enables seamless real-time control and monitoring from PLCs, enabling remote diagnostics and centralized asset management. Enhanced short-circuit protection and protective features further reduce unplanned downtime and equipment damage, while 240 V operation ensures compatibility with common plant voltages. Overall, ACS255 offers a compact, plug-and-play solution that accelerates integration within existing ABB drive ecosystems and minimizes spare-part variety for maintenance teams.
