The ABB PSRC105-600-70 is a compact and reliable softstarter designed for smooth starting and stopping of three-phase AC motors in industrial applications. As part of the specialised ABB PSRC softstarter series, it is optimised for motor control applications requiring fixed settings, reduced starting current and reliable operation, including scroll compressor systems.
This softstarter provides controlled motor acceleration through voltage ramp technology while reducing mechanical stress and electrical load during starting. The PSRC series combines compact construction with built-in bypass functionality, making installation easier and improving energy efficiency during normal motor operation.
With a rated operational current of 105 A and a 208–600 V AC motor supply range, the ABB PSRC105-600-70 is suitable for medium-sized three-phase motors used in compressors, pumps, fans, conveyors and industrial machinery.
