Schneider ATS46D47N Soft Starter

Feature & Principle

It is Schneider Altistart 46 series torque-controlled soft starter. It adopts thyristor voltage regulation and patented torque control algorithm, realizes smooth ramp start and soft stop, suppresses starting inrush current and water hammer effect. Built-in bypass contactor, low heat loss after startup. It integrates overload, phase loss, current unbalance protection, suitable for fans, pumps and conveyors. This model is discontinued for maintenance spare.
