ATS22C11Q, Altistart 22 Series Soft Starter, 55 kW, 110 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: ATS22C11Q

The Schneider Electric ATS22C11Q (Altistart 22) is a compact 3‑phase motor soft starter rated for 110 A nominal. Verified manufacturer data specifies motor power capability up to 39 kW at 230 V and up to 55 kW at 400–440 V, making this unit suitable for common industrial motor sizes used on pumps, fans, compressors and simple conveyor systems. The ATS22C11Q supports a wide supply voltage range (230…440 V AC, 50/60 Hz) and provides torque-controlled, current-limited starts (start current limited to approximately 3.5 × In) to reduce mechanical stress and limit inrush current. The model includes an internal bypass to reduce heat dissipation after starting, built-in motor monitoring with electronic overload / motor thermal model and a PTC thermistor input for thermal protection, plus RS485 (Modbus) communication for basic fieldbus connectivity. In practice, this Schneider ATS22 soft starter is a straightforward choice where reliable, compact industrial motor starting and simple monitoring are required in panel- or enclosure-mounted installations.
