ABB PSR3-600-70 Softstarter (1SFA896103R7000)

The ABB PSR3-600-70 is a compact softstarter engineered for small three-phase motors with a current rating of 3.9 A and voltage range of 208 to 600 V AC. Designed for reliability and ease of integration, it features two-phase controlled soft start and stop via voltage ramp, along with an integrated bypass contactor for reduced wiring and improved energy efficiency.

This model supports up to 100 starts per hour and is ideal for use in pumps, fans, compressors, and conveyor systems. It includes front-facing potentiometers for ramp time and voltage control, a built-in RUN signal relay, and LED status indicators. The PSR series is compatible with ABB’s manual motor starters (MMS) and can be fieldbus-enabled with optional plug-in adapters.
