WEG SSW060604T2257PSZ Soft Starter

Feature & Principle

It is a microprocessor digital soft starter of WEG SSW06 series. It adjusts the thyristor firing angle to change the output voltage, realizing smooth ramp start and stop of three-phase asynchronous motor, reducing starting inrush current and mechanical impact. Integrated bypass contactor will short the thyristor after motor full-speed operation to reduce heat loss. It has torque control, pump anti-water hammer function, thermal overload, phase loss, unbalance, overvoltage and undervoltage protection. Optional Modbus, Profibus communication card for upper system monitoring.
