1SFA896106R1100

ABB 1SFA896106R1100 PSR12-600-11 Soft starter is a compact 12 A three-phase motor soft starter from ABB’s PSR series. It is designed for smooth starting and stopping of small three-phase AC induction motors, with a 208–600 V AC main operating voltage and 24 V AC/DC control supply. ABB identifies this exact part number as PSR12-600-11. The soft starter uses two-phase controlled voltage-ramp starting and stopping, helping reduce mechanical shock, abrupt starting torque, belt and coupling stress, and electrical disturbances compared with direct-on-line starting. It also incorporates a built-in bypass, reducing energy losses and heat generation after the motor reaches full operating speed. The PSR family is designed for compact motor-control applications and can handle up to 100 starts per hour. Typical applications include pumps, fans, compressors and conveyors.
