Description
The PSR45-600-70 Softstarter from ABB is a compact and reliable motor starting solution designed for small to medium three-phase motors. Rated at 45 A with an operational voltage range of 208–600 V AC, it delivers smooth acceleration and deceleration through two-phase voltage ramp control, reducing mechanical stress, electrical peaks, and wear on driven equipment.
This soft starter features an integrated bypass contactor for improved energy efficiency and simplified installation. Adjustable start and stop ramps, configured via front-mounted potentiometers, allow precise tuning to suit application requirements. Status feedback is available through RUN and TOR relay outputs, enabling easy integration into control systems.
The PSR series is ideal for applications such as pumps, fans, compressors, and conveyors, where reliable soft starting enhances equipment lifespan and operational stability. Its compact design, basic functionality, and capability of handling up to 100 starts per hour make it a practical and cost-effective solution for industrial and commercial motor control panels.
