SSW06 – Soft Starter (2.2 to 1375 kW)

SSW06 – Soft Starter (2.2 to 1375 kW)

Soft-Starters are static starters that accelerate, decelerate and protect three-phase induction motors in power ratings from 2.2 to 1375 kW.

SKU: SSW06 Categories: ,



SSW-06 Series Soft-Starter are static starters intended to accelerate, decelerate and protection of three phase induction motors. The control of the voltage applied to the motor by the means of the thyristors triggering angle variation, allows the soft-start to start and stop smoothly an electric motor.

With adequate adjustments of the variables, the torque produced is adjusted to the needs of the load, so the required current is going to be as low as possible for the starting procedure.

WEG Soft-Starter SSW-06 series, micro processed and full digital, are products with state-of-the-art technology and have been produced to ensure the best starting and stopping performance of induction motors, presenting themselves as a complete and low cost solution.

The human-machine interface allows easy adjustment of the parameters what helps commissioning and operation. The built-in Pump Control function allows an efficient control over pumps, avoiding overshoots.

Note: SSW06 Soft-Starter Series were designed for exclusively industrial or professional use.
