ABB 1SFA897105R7000 PSE45-600-70 Soft starter is a 45 A three-phase general-purpose soft starter from ABB’s PSE series, designed for controlled starting and stopping of small-to-medium AC induction motors. It operates on a 208–600 V AC main circuit and uses a 100–250 V AC, 50/60 Hz control supply. ABB India currently rates this exact model for 22 kW / 30 HP motor applications. The PSE45-600-70 uses two-phase control and provides soft start and soft stop through voltage or torque ramp control. It incorporates a built-in bypass, which reduces heat generation and energy losses once the motor reaches normal operating speed. Compared with ABB’s basic PSR series, the PSE range includes additional motor-control and protection functions such as current limiting, kick start, electronic overload protection, underload protection, locked-rotor protection, analog output, and built-in Modbus RTU communication. It also has an illuminated display and provides RUN, TOR, and Event relay outputs. Typical applications include pumps, fans, compressors, conveyors, HVAC equipment, water-treatment systems, and industrial machinery.
