Here is the data sheet (PDF download). Please ask us for this device separately.
The soft starter SAS [3 – 11 kW] is a compact, single-phase controlled soft starter for the safe and uniform running up of three-phase and pole-switchable motors. It reduces mechanical loads during start-up, extends the service life of the drives and can be used universally in 230 V- and 400 V networks.
