Why Choose the ABB PSRC85-600-70 Softstarter?
The ABB PSRC85-600-70 is a compact and reliable softstarter designed for controlled starting and stopping of three-phase motors in industrial automation, compressor and machinery applications. As part of the ABB PSRC softstarter series, it provides a simple and efficient solution for reducing motor starting current, minimising mechanical stress and improving equipment reliability.
This softstarter features ABB’s compact PSRC technology with two-phase controlled soft start through a voltage ramp. The integrated bypass function simplifies installation, reduces heat generation during normal operation and improves energy efficiency once the motor reaches full speed.
With a rated operational current of 85 A and a main supply voltage range of 208–600 V AC, the PSRC85-600-70 is suitable for medium-sized three-phase motors used in compressors, pumps, fans, conveyors and industrial machinery.
