ATS22D75Q, Altistart 22 Series Soft Starter, 37 kW, 75 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: ATS22D75Q

The Schneider Electric ATS22D75Q is an Altistart 22 soft starter rated for 75 A continuous use and designed for three-phase supply voltages in the 230…440 V range (supply limits typically specified 195–484 V). It is factory-set to 69 A and is specified for typical motor power ratings of 18.5 kW at 230 V and 37 kW at 400–440 V, making it suitable for small to medium three‑phase induction motors used in pumps, fans, compressors and material‑handling equipment. The ATS22D75Q implements torque (current) control with current-limited starting (specified as current-limited to 3.5 × In), which reduces mechanical shock and limits inrush current during starts. Practical features verified for this SKU include an internal bypass to reduce heat and noise during run, integrated motor overload protection, and an RS‑485 multipoint communication interface for basic monitoring or configuration. Typical buyers are maintenance engineers and procurement teams specifying compact, convection‑cooled soft starters to replace direct-on-line starts or to add soft‑start functionality where simple, robust control and reduced mechanical wear are required.
