ACS355-03U-24A4-2

The ABB ACS355-03U-24A4-2 AC drive delivers precise motor control for pump and fan applications with minimal overload demand. Rated at 7.5HP (24.4A) and compatible with 3-phase 200-240V input, this open-type drive is optimized for variable torque loads where consistent performance is critical. Measuring 9.29 x 6.65 x 6.65 inches, the ACS355 integrates seamlessly into compact control panels while maintaining a 1.5x overload capacity for reliable operation under fluctuating conditions. Designed for OEMs and system integrators, it supports direct-on-line or soft-start configurations, reducing mechanical stress on driven equipment. The drive’s open enclosure design simplifies heat dissipation, making it ideal for indoor environments where space and airflow are considerations. With ABB’s proven reliability in low-voltage drives, the ACS355-03U-24A4-2 ensures energy-efficient operation with minimal maintenance requirements. Typical applications include HVAC systems, water pumping stations, and industrial ventilation where variable speed control enhances system efficiency.
