ABB 1SFA897115R7001 PSE370-600-70-1 Soft starter is a 370 A three-phase soft starter from ABB’s PSE series, designed for smooth starting and stopping of medium- to high-power AC induction motors. It operates over a 208–600 V AC main circuit range with a 100–250 V AC, 50/60 Hz control supply. ABB identifies this exact order code as PSE370-600-70-1 and rates it for up to 200 kW motor applications. The PSE370-600-70-1 uses two-phase control and supports soft starting and soft stopping through either a voltage ramp or torque ramp. It includes a built-in bypass, reducing heat generation and energy losses after the motor reaches normal operating speed. The unit also provides advanced functions including current limiting, kick start, analog output, electronic overload protection, underload protection, and locked-rotor protection. For monitoring and automation integration, the unit includes an illuminated display, RUN/TOR/Event relay outputs, and built-in Modbus RTU communication. Optional Fieldbus connectivity is also possible through an external adapter and Fieldbus Plug. ABB positions the PSE as a general-purpose soft starter suitable for applications such as pumps, fans, compressors, conveyors, HVAC systems, water-treatment installations, and industrial process machinery.
