Product Overview
The ABB PSTX170-600-70, order code 1SFA898111R7000, is an advanced PSTX series soft starter designed for controlled starting and stopping of three-phase industrial motors. It has an ABB catalogue-rated operational current of 170A and supports an operating voltage range of 208–600V AC, with a separate 100–250V AC control supply. The unit is rated for 90kW at 400V and 110kW at 500V under IEC motor rating conditions. Its integrated bypass reduces energy consumption during normal motor operation, while voltage and torque ramp control help manage motor starting and stopping. The PSTX platform also provides electronic overload protection, current limiting, built-in Modbus RTU communication, programmable relay outputs and additional motor control functions. These capabilities make the PSTX170-600-70 suitable for appropriately rated industrial pumps, fans, compressors and conveyor applications.
