Softstarter Schneider Electric Altistart ATS01N222QN 3-phase 380–415VAC 22A for 7.5–11 kW motors

Schneider Electric Altistart ATS01N222QN is a 3-phase softstarter designed for 380–415 VAC systems and rated for 22 A. Intended for motors from 7.5 to 11 kW (400 V), this softstarter provides controlled ramp-up and ramp-down of motor torque to limit inrush current and reduce mechanical stress on drivetrains. The device supports reliable starting of conveyors, pumps and compressors while helping to extend equipment life and stabilise processes in industrial and commercial installations.

Advantages

The Altistart ATS01N222QN reduces peak starting currents and smooths torque transmission during start and stop sequences, which decreases wear on couplings, belts and gearboxes. Its compact three-phase design simplifies installation in control panels and offers straightforward integration with motor circuits for standard applications. By managing starting profiles and stopping behaviour, it helps maintain more consistent process performance and lowers the probability of transient disturbances on the supply network.

Suitable for

• Starting and stopping three-phase induction motors rated 7.5–11 kW at 400 V
• Conveyors and material handling equipment with medium starting torque requirements
• Pumps and fans where reduced water hammer or mechanical shock during start/stop is desired
• Compressors and HVAC systems that benefit from controlled start sequences

When it may not be suitable

This softstarter is not intended for single-phase motors or for three-phase motors outside the specified power range; motors with higher starting torque requirements or installations that require full electronic motor protection and advanced communications may need a different model. Applications that demand precise speed control during operation (variable-speed drive functions) are better served by a variable frequency drive (VFD) rather than a softstarter.

Key specifications

• Supply voltage: three-phase 380–415 VAC
• Rated current: 22 A
• Compatible motor power range (at 400 V): 7.5–11 kW
• Function: soft start and soft stop (controlled torque ramping)
• Typical applications: conveyors, pumps, compressors, fans
• Form factor: compact three-phase softstarter for panel mounting

How to use

Install the Altistart ATS01N222QN within an appropriate control cabinet following local electrical codes and Schneider Electric installation guidelines. Connect the incoming three-phase supply and motor wiring to the dedicated terminals, and configure start/stop control inputs and basic ramp settings according to the motor nameplate and load requirements. Adjust ramp time and initial torque settings to achieve the desired balance between reduced inrush current and adequate starting torque. Verify protective devices such as fuses or circuit breakers are selected to match the reduced starting characteristics and the rated current of the softstarter.

What to consider before purchase

• Confirm motor power and rated voltage fall within 7.5–11 kW at 400 V and 380–415 VAC supply range
• Assess starting torque requirements of the driven equipment to ensure a softstarter is appropriate
• Check whether additional motor protection or communication features are required beyond basic soft starting
• Verify panel space and cooling conditions for mounting a compact three-phase softstarter

Recommendations

For best results, set ramp times to the minimum needed to limit inrush current while maintaining reliable starts. Periodically inspect electrical connections and cooling conditions, and follow Schneider Electric maintenance guidance to ensure consistent performance and long service life.
