Schneider ATS22D47Q Altistart 22 47A 22kW 400V Soft Starter with Integrated Bypass

Product Overview

The Schneider ATS22D47Q is a 47 A three-phase soft starter from the Altistart 22 series. It provides controlled motor acceleration and deceleration to reduce starting current, mechanical shock and stress on industrial drive systems.

This Q-suffix version supports a 230–440 VAC main circuit and a 230 VAC control supply. It is commonly used with motors up to approximately 22 kW at 400 V under suitable starting and environmental conditions.

The ATS22D47Q integrates a six-thyristor controlled power stage, bypass contactor, adjustable current limitation, motor thermal protection, local keypad and Modbus serial communication.

Technical Specifications

Compatible System and Applications

The ATS22D47Q is suitable for pumps, fans, compressors, conveyors, mixers and other three-phase motor applications. Its 47 A rating covers a widely used industrial motor range and provides useful replacement value for process and machine-control systems.

The approximate 22 kW value is a selection guide for typical 400 V motors. Final selection must be based on actual motor current and starting duty, particularly for high-inertia loads, loaded conveyors, crushers or applications with long acceleration times.

Maintenance and Replacement Notes

Confirm that the installed unit is ATS22D47Q and not ATS22D47S6 or ATS22D47S6U. The suffix determines both the permitted main-circuit voltage range and control-supply voltage.

Inspect the integrated bypass contactor for contact wear and bypass faults. Also examine the thyristor power stage, cooling passages, power terminals, control terminals and communication settings.

Before commissioning, confirm motor thermal settings, current limitation, acceleration and deceleration parameters, line protection, wiring arrangement and Modbus address, baud rate and parity.
