ATS22D75S6, 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: ATS22D75S6

The Schneider ATS22D75S6 is an Altistart 22 soft starter rated for a 75 A starter rating (factory setting 65 A) and intended for three-phase supply voltages across the 230–600 V class. It is specified to reliably start asynchronous motors up to 18.5 kW at 230 V, 37 kW at 400–440 V, and up to 45 kW at 500 V, making it suitable for medium-power pumps, fans and general-purpose industrial machinery. The ATS22D75S6 provides torque-controlled starting (current limited to 3.5 × In) to reduce mechanical stress and limit inrush current, and includes an internal bypass to reduce dissipation during run. For system integration it supports RS-485 serial communication (Modbus) and offers built-in motor protection functions including phase-failure detection and thermal protection features. Typical users are maintenance engineers and procurement teams specifying a compact, straightforward motor soft starter for industrial motor starting where pump and fan duty, simple configuration and reliable protection are required.
