ATS22C48Q, Altistart 22 Series Soft Starter, 250 kW, 480 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: ATS22C48Q

The Schneider ATS22C48Q is an ATS22-series soft starter rated for heavy-duty industrial motor starting. It has a rated operational current of 480 A and is specified for motor power up to 132 kW at 230 V and up to 250 kW at 400 V / 440 V, making it suitable for large asynchronous (squirrel-cage) motors used in pumps, fans and other continuous-duty applications. The unit is designed for three-phase supply voltages in the 230…440 V range (supply limits typically cited as 195…484 V) and supports start control using torque/current-limited starting (torque control with current limiting). Key practical features verified for this model include an integrated bypass contactor to minimise losses after start, built-in motor protection functions (thermal protection, overload and phase-failure detection), and communication capability (Modbus/RS485 with RJ45 connector on standard configurations) for integration with PLC/SCADA. ATS22C48Q is aimed at procurement and engineering teams who need a compact soft starter that handles high motor power, reduces mechanical stress and starting current, and integrates easily into industrial control systems.
