PSR25-600-70 Softstarter 25A 208-600V AC 11kW | ABB

The Original New ABB PSR25-600-70 is a compact, basic-functionality softstarter from the ABB PSR series, designed to provide smooth, controlled motor starting and stopping for small three-phase motors. Rated at 25 A with an operational voltage range of 208…600 V AC, it is suitable for motors up to 11 kW at 400 V. Featuring a built-in bypass contactor for energy savings and easy installation, the PSR25-600-70 reduces mechanical stress on driven equipment and extends motor life. Three front-panel potentiometers allow straightforward adjustment of start/stop ramps and initial voltage, making it an ideal solution for pumps, fans, compressors, and conveyors.
