ABB 1SFA897104R7000 PSE37-600-70 Soft starter is a 37 A three-phase general-purpose soft starter from ABB’s PSE series, designed for smooth starting and stopping of small to medium AC induction motors. It operates on a 208–600 V AC main circuit with a 100–250 V AC, 50/60 Hz control supply. ABB India rates this exact model at 18.5 kW / 25 HP. The PSE37-600-70 uses two-phase control and supports both voltage-ramp and torque-ramp soft start/soft stop. It includes a built-in bypass, which reduces losses and heat once the motor reaches normal running speed. The PSE range also provides current limit, kick start, analog output, electronic overload protection, underload protection, and locked-rotor protection.
