ATS22D75S6U, Altistart 22 Series Soft Starter, 37 kW, 75 A, 230 to 600V 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: ATS22D75S6U

The Schneider ATS22D75S6U is an Altistart 22 motor soft starter rated for 75 A nominal operation (Ie) and intended for three-phase supplies in the 230–600 V range. Factory and distributor datasheets show typical motor power compatibility of 18.5 kW at 230 V and 37 kW at 400 V (inline connection), making this unit suitable for medium‑power motors commonly found on pumps, fans, compressors and material‑handling equipment. The device uses torque (current) control with a current‑limit start mode (listed as current limited to approx. 3.5×In) to limit starting current and manage torque during acceleration — a practical approach for applications that require reduced mechanical stress and controlled ramp-up. Verified product highlights include an internal bypass contactor to minimise heat dissipation during run, integrated motor overload protection, and compatibility with Schneider configuration tools (SoMove) for faster setup and spare replacement. The ATS22D75S6U is aimed at engineers and procurement teams seeking a compact, straightforward soft starter for standard industrial motor starting where smooth starts, reduced inrush and simple commissioning are priorities.
