ATS22C17S6, Altistart 22 Series Soft Starter, 90 kW, 170 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: ATS22C17S6

The ATS22C17S6 Altistart 22 soft starter is specified for a rated operational current of 170 A and supports motor power ratings across common industrial voltage classes: 45 kW at 230 V, 90 kW at 400–440 V, and up to 110 kW at 500 V. The unit is designed for three-phase supply voltages from 230 to 600 V (manufacturer limits typically shown as -15% / +10%), making it suitable for standard low- and medium-voltage industrial motor installations. Typical motor sizes covered by this model include medium-power pumps, fans and compressors in the 45–110 kW band depending on system voltage, so it is well matched to water-moving, ventilation and general mechanical loads where reduced inrush and controlled torque are required. This SKU implements torque (current‑limited) starting — the starter limits starting current to approximately 3.5 × In — and includes an internal bypass, which reduces thermal dissipation after the motor reaches running speed. Those verified features help lower mechanical stress during start, reduce energy losses during run, and simplify panel wiring and commissioning for procurement and engineering teams specifying reliable soft starters for industrial motor starting.
