ABB 1SFA896114R1100 PSR85-600-11 Soft starter is an 85 A three-phase motor soft starter from ABB’s PSR series, designed for smooth acceleration and deceleration of AC induction motors. It operates on a 208–600 V AC main circuit and uses a 24 V AC/DC control supply. This model is typically used for around 45 kW / 60 HP motor applications. The PSR85-600-11 uses two-phase controlled voltage-ramp technology for soft starting and soft stopping. This reduces mechanical shock, excessive starting torque, belt and coupling wear, and electrical stress compared with direct-on-line starting. The unit includes a built-in bypass, helping reduce heat generation and power losses once the motor reaches full operating speed. Typical applications include pumps, fans, compressors, conveyors, HVAC systems, industrial machinery and motor-control panels.
