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. The PST Softstarter can be used with or without a by‑pass contactor. The larger sized models include a built‑in bypass contactor. The PST Softstarter can be selected according to the rated motor power in normal duty applications like pumps, compressors, elevators, escalators, short conveyor belts and bow thrusters.
