ABB 1SFA896109R7000 PSR30-600-70 Soft starter is a compact 30 A soft starter from ABB’s PSR series, designed for controlled starting and stopping of three-phase AC motors. It operates with a main circuit voltage of 208–600 V AC and a control supply voltage of 100–240 V AC, 50/60 Hz. ABB India lists this model for approximately 15 kW / 20 HP motor applications. The PSR30-600-70 uses two-phase controlled voltage ramp technology for soft start and soft stop. This reduces mechanical stress, sudden torque, starting-current disturbances, belt wear, coupling shock, and pressure surges compared with direct-on-line starting. It also includes a built-in bypass contactor, helping reduce heat generation and energy losses after the motor reaches normal operating speed. Typical applications include pumps, fans, compressors, conveyors, HVAC equipment, industrial machinery, and motor control panels.
