WEG Soft-Starter SSW-05

WEG Soft-Starter SSW-05

WEG soft starters from IMAG are fitted with micro processors. They are high-tech and were designed to ensure the highest performance during starts and stops of induction motors.


Soft-Starters are electronic starters designed to accelerate, decelerate and protect three-phase induction motors, controlling the voltage applied on the motor.

The SSW-05 Plus Micro Soft-Starters, with DSP control (Digital Signal Processor) have been designed to supply an excellent performance during starting and stopping electric motors with excellent cost / benefit ratio.

The Operator Interface allows easy parameter setting, simplifying the start-up and operation activities.

The SSW-05 Plus Micro Soft-Starters are compact, optimising the space in electrical panels and already incorporates all protections for the driven motor.
