    The PST range is a microprocessor based softstarter designed with the latest technology for soft start and soft stop of motors.
    The PST Softstarter has several advanced motor protection features as standard.
    The four button keypad and the logic structure of the menu make the installation, commissioning and operation easy.
    It is possible to choose between 12 different languages. The PST Softstarter can be used with or without a by-pass contactor except for the larger sizes PSTB370 ... PSTB1050 where the by-pass contactor is already built-in.
    The PST Softstarter can be selected according to the rated motor power in normal duty applications like pumps, compressors, el e- vators, escalators, short conveyor belts and bow thrusters.

    For heavy duty applications like centrifugal fans, crushers, mixers, mills, stirrers and long conveyor belts, select a softstarter from
