ABB 1SFA897114R7001 PSE300-600-70-1 Soft starter is a 300 A three-phase soft starter from ABB’s PSE series, designed for controlled starting and stopping of medium- to high-power 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 lists this exact order code as PSE300-600-70-1, commercially rated for 160 kW motor applications. The PSE300-600-70-1 uses two-phase control and provides soft start and soft stop through voltage-ramp or torque-ramp control. It includes a built-in bypass, helping reduce heat generation and power losses once the motor reaches normal operating speed. The unit also provides current limiting, kick start, analog output, electronic overload protection, underload protection, and locked-rotor protection. For communication and system integration, the PSE platform supports an illuminated display, relay outputs, built-in Modbus RTU, and optional Fieldbus Plug connectivity. Typical applications include pumps, fans, compressors, conveyors, HVAC systems, water-treatment plants, and industrial process machinery.
