ABB PSR3-600-70 is a three-phase soft starter (model 1SFA896103R7000) designed to smoothly start motors up to 1.5 kW, helping to limit inrush and protect wiring. It supports a maximum main voltage of 600 V and a control supply of 100–240 V AC at 50/60 Hz, with a continuous current rating around 3.9 A. A Run signal relay output (normally open) is provided to indicate when the starter is actively controlling the motor, and the PSR3-600-70 is commonly used to drive small to mid-size three-phase motors such as pumps, fans, and conveyors in automation applications, reducing peak electrical demand during startup.
