Overview

The ABB PSR3-600-70 Softstarter (SKU: PSR3-600-70) is a compact, two-phase controlled softstarter designed for small three-phase motors with nominal currents from 3 to 105 A. Rated for 208 to 600 V AC operation and 100 to 240 V AC control voltage at 50/60 Hz, this unit delivers reliable soft start and stop functionality via a voltage ramp, reducing mechanical stress and electrical surges during motor startup and shutdown. The built-in bypass minimizes energy loss during full-speed operation, enhancing system efficiency while simplifying installation. Three front-panel potentiometers allow precise adjustment of start/stop ramps and timing, while a normally open (NO) relay output provides a RUN signal for monitoring. Capable of handling up to 100 starts per hour, the PSR3-600-70 is ideal for applications such as pumps, fans, compressors, and conveyors where controlled motor acceleration is critical. Mechanical connection kits enable seamless integration with ABB’s manual motor starters (MMS), and optional Fieldbus communication (via external adapter and plug) supports advanced automation integration. Part of ABB’s PSR range, this softstarter prioritizes space efficiency without sacrificing essential performance, making it a cost-effective solution for industrial motor control. The PSR series is the most compact softstarter line in ABB’s portfolio, offering basic functionality with a focus on simplicity and reliability. It supports two-phase control for balanced motor operation and includes protections for motor safety. Fieldbus communication is available as an add-on for integration into automated systems.
