ATS22C11S6, Altistart 22 Series Soft Starter, 55 kW, 110 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: ATS22C11S6

The Schneider Altistart ATS22C11S6 is a compact motor soft starter rated for 110 A continuous operation and designed for 3-phase supply voltages from 230 to 600 V AC. Depending on system voltage, the ATS22C11S6 is suitable for motors up to approximately 30 kW at 230 V, 55 kW at 400–440 V and up to 75 kW at 500 V, making it appropriate for medium-power pumps, fans, compressors and conveyor drives used in industrial motor starting applications. This model incorporates an internal bypass to reduce heat dissipation during run, torque-control start (current-limited start up to approximately 3.5 × In) to limit inrush and protect mechanical systems, and integrated motor protection functions including overload and phase-failure detection. For system integration, the unit offers RS485/Modbus communication and is compatible with SoMove configuration tools, simplifying commissioning and spare replacement. The ATS22C11S6 targets engineers and procurement teams seeking a straightforward, reliable soft starter to reduce mechanical stress, limit starting current and add basic motor protection without complex drive features.
