ATS22C25Q, Altistart 22 Series Soft Starter, 132 kW, 250 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: ATS22C25Q

The Schneider ATS22C25Q Altistart 22 is a line-mounted soft starter rated for 250 A nominal operation, designed for three‑phase industrial supplies. Its rated operating voltage is 230–440 V (supply limits 195–484 V), and it controls motors up to 75 kW at 230 V and up to 132 kW for inline (Ue) connection at 400–440 V; higher ratings apply when the motor is connected in delta (eg. 110 kW at 230 V delta, 220 kW at 400 V delta) as specified by Schneider. The ATS22C25Q uses torque (current‑based) control with a current limit behaviour (start current limited to about 3.5 × In) to manage inrush and deliver smooth acceleration, reducing mechanical stress on pumps, fans, compressors and material‑handling drives. Standout, verified features for this SKU include an integrated bypass to reduce heat dissipation during run, built‑in motor overload and thermal protections, and serial communication support (Modbus/RS‑485) for basic remote status and monitoring. The device is intended for straightforward industrial motor starting where reliable current limiting, torque control and a compact, serviceable design are required.
