Schneider ATS22D88Q Altistart 22 Soft Starter 88A 400-440V 45kW Internal Bypass

The Schneider Electric ATS22D88Q is a three-phase soft starter from the Altistart 22 series, designed for smooth starting of asynchronous motors. Rated at 88 A with an integrated internal bypass, it supports motor powers of 22 kW at 230 V and 45 kW at 400-440 V. Torque-controlled starting limits inrush current to 3.5 In, making it well suited for pumps and fans.
