ATS22C25S6U, Altistart 22 Series Soft Starter, 132 kW, 250 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: ATS22C25S6U

The Schneider Altistart ATS22C25S6U is a line-connected motor soft starter rated for 250 A continuous operation at 40 °C. It supports three-phase supply voltages from 208 V up to 600 V AC and is specified for motors up to 132 kW (at 400 V) or 75 kW (at 230 V) in standard switching configurations, making it suitable for medium- to large-size industrial motors such as pumps, fans, compressors and conveyor drives. This model uses torque (current-limited) start control to limit inrush current and manage starting torque (current-limited to a defined multiple of In), which reduces mechanical stress and electrical network disturbance during starting. Key verified features for the ATS22C25S6U include an internal bypass to reduce heat dissipation and acoustic noise during running, integrated motor overload protection, and a 110 V control supply option. Specify this soft starter when you need a compact, robust motor soft starter for industrial motor starting where controlled ramp-up, built-in bypassing and embedded motor protection are required.
