ABB 68672961 Motors & Drives - ACS800-U31-0050-5, Pcont.max 45 kW
Part Number: 68672961
Quick Summary
ABB 68672961 ACS800-U31-0050-5 is a motor drive for precise motor control in industrial automation. Engineers often struggle to balance performance, energy efficiency, and motor protection under varying loads. In practice, CE compliance and IP-rated enclosures are essential, while SIL considerations may apply for safety-critical lines. Leveraging this drive supports reliable automation projects, reduces downtime, and aligns with modern plant-wide optimization strategies.
Product Information
The drive delivers continuous power up to 45 kW and current up to 70 A, supporting mid-size motors used in pumps, fans, and conveyors. This capability translates to reliable speed and torque control across loading conditions, reducing mechanical wear and energy waste in automated processes. Built-in protections and diagnostics provide immediate fault detection and safe operation, minimizing unplanned downtime and enabling easier maintenance planning in process lines with volatile loads. Compact, panel-friendly design and straightforward wiring simplify installation and commissioning, while compatibility with ABB's drive ecosystem enables seamless integration with existing motor control schemes and fieldbus networks, reducing retrofit risk. Energy efficiency gains come from optimized motor control and adjustable ramping profiles, which can reduce energy consumption in variable torque applications. In practice, energy savings of 10–25% are common for fans and pumps. Operational insights from diagnostics support proactive maintenance and lifecycle planning, while ABB's global support and spare parts availability improve long-term total cost of ownership.
