ABB 1SFA897107R7000 PSE72-600-70 Soft starter is a 72 A three-phase general-purpose soft starter from ABB’s PSE series, designed for controlled acceleration and deceleration of 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 rates this exact model for 37 kW / 50 HP motor applications. The PSE72-600-70 uses two-phase control and supports both voltage-ramp and torque-ramp soft start/soft stop. It includes a built-in bypass, reducing losses and heat after the motor reaches normal operating speed. It also provides advanced functions such as current limiting, kick start, analog output, electronic overload protection, underload protection, and locked-rotor protection. The unit includes an illuminated display, RUN/TOR/Event relay outputs, and built-in Modbus RTU communication. ABB positions the PSE range as a general-purpose soft starter suitable for pumps, fans, compressors, conveyors, HVAC systems, water-treatment equipment, and industrial machinery.
