ATS22C17Q, Altistart 22 Series Soft Starter, 90 kW, 170 A, 230 to 440V AC

Schneider Electric ATS22 Soft Starter Series – Overview

Schneider Electric ATS22 soft starters are compact and reliable motor starting solutions designed for smooth acceleration and deceleration of asynchronous motors in standard industrial applications. The ATS22 series focuses on reducing mechanical stress, limiting starting current, and simplifying motor starting without advanced digital control requirements. With a proven design and straightforward configuration, ATS22 soft starters are commonly used for pumps, fans, compressors, conveyors, and general-purpose machinery where controlled motor starting is required.

Product Description: ATS22C17Q

The Schneider Altistart 22 ATS22C17Q is a compact motor soft starter rated for 170 A nominal operational current and designed for three‑phase supplies in the 230–440 V range. It is specified to control motors up to approximately 45 kW on a 230 V supply and up to 90 kW on a 400–440 V supply (standard line connection ratings). The ATS22C17Q uses torque (current‑limited) start control — limiting starting current up to about 3.5 × In — which reduces mechanical stress and peak network loading compared with direct-on-line starts. This model includes an internal bypass contactor to reduce heat dissipation during run and an integrated motor overload protection function, making it appropriate for common industrial motor loads such as centrifugal pumps, fans, compressors and conveyor drives.

Who this is for: procurement teams and engineers specifying reliable, compact soft starters for straightforward industrial motor starting tasks where controlled start torque, reduced inrush, and a built‑in bypass are required. Practical tip: select ATS22C17Q when you need a simple, robust soft starter for standard pump/fan/compressor applications up to the verified kW limits at the target supply voltage rather than a feature‑rich digital starter.
