Schneider ATS22C14Q Soft Starter for Asynchronous Motor, Altistart 22, Control 2

The Schneider Electric ATS22C14Q is a three-phase soft starter from the Altistart 22 series, engineered to control asynchronous motors up to 37 kW at 230 V or 75 kW at 400/440 V. With torque-controlled starting that limits inrush current to 3.5 In and a factory-set current of 131 A, it delivers smooth motor acceleration for pump and fan applications.

Features and benefits:

• Torque-controlled starting limits inrush current to 3.5 In, reducing mechanical stress on motor and driven load
• Integrated internal bypass reduces heat dissipation during steady-state run, improving energy efficiency
• Built-in Modbus RS485 communication enables integration with PLCs and SCADA systems
• Three-layer protection - phase loss, motor thermal, and starter thermal - for enhanced system reliability
• Supports both direct motor connection and in-line connection with delta-wound motor windings
• Wide supply voltage tolerance (195...484 V) and frequency range (45...66 Hz) suits global installations

Applications:

• Pump systems requiring controlled ramp-up to prevent water hammer and pipeline stress
• Fan and HVAC installations where smooth acceleration reduces belt and coupling wear
• High-inertia industrial machinery requiring gradual torque build-up on start
• Networked automation panels requiring Modbus connectivity for remote monitoring and control
• Three-phase motor control in manufacturing and utilities across 230...440 V supply networks

Compliant with IEC 60947-4-2. Part of the Schneider Electric Altistart 22 range.
