ABB PSR30-600-70 Three-Phase Soft Starter For Motors

The ABB PSR30-600-70 Three-Phase Soft Starter for Motors delivers smooth starting and stopping of three-phase AC motors while reducing inrush current and mechanical stress. It handles a Rated Operational Current of 30 A and a Rated Operational Voltage of 208–600 V AC, with a voltage ramp soft start and a built-in bypass contactor for reliable operation mounted on DIN rail or panel. This model is commonly used in pumps, conveyors, HVAC equipment, and general manufacturing where gradual motor acceleration improves process stability and extends equipment life, with applications in water and wastewater facilities, material handling, ventilation and cooling, packaging machinery, and more. Control voltage is wide-range (model dependent), and the ABB PSR30-600-70 has common replacements PSR25-600-70, PSE30-600-70, and PSTX30-600-70.
