1SFA896111R1100

ABB 1SFA896111R1100 PSR45-600-11 Soft starter is a compact 45 A three-phase soft starter from ABB’s PSR series, designed for smooth starting and stopping of three-phase AC induction motors. It operates across a 208–600 V AC main circuit voltage range and uses a 24 V AC/DC control supply. ABB identifies this exact part number as PSR45-600-11. The unit uses two-phase controlled voltage-ramp soft starting and soft stopping, helping reduce sudden torque, mechanical shock, electrical disturbances, belt wear and coupling stress compared with direct-on-line starting. It incorporates a built-in bypass, which reduces power losses and heat generation once the motor reaches normal operating speed. The PSR family can manage up to 100 starts per hour and is commonly used for pumps, fans, compressors and conveyors.
