Schneider Electric ATS22 Soft Starters — The B2B Standard for Compact Multi-Phase Motor Control

The Schneider Electric Altistart 22 (ATS22) soft starter range is one of the most widely specified choices for HVAC, municipal, and B2B industrial systems, covering capacities from 4 to 315 kW. It represents a symmetrical three-phase thyristor soft starter featuring fully integrated bypass contactors across all models. The ATS22 combines precise three-phase control with built-in motor overload safety (Class 10/20 adjustments) and a straightforward interface for rapid setup.

Typical Applications for Schneider ATS22

• Municipal Water and Waste Systems: Symmetrical three-phase control allows precise water deceleration, completely preventing line mechanical wear from water hammer.
• Industrial Screw Compressors: Current-limited start profiles reduce high starting currents, preventing electrical line drops.
• Medium-Duty Packaged Conveyors: Smooth torque building eliminates starting jerks, protecting motor shaft keys and coupling belts.

What Differentiates Schneider ATS22 from Competitors

Symmetrical three-phase regulation ensures a highly balanced magnetic field in the motor stator, reducing shaft vibration during acceleration cycles.

When Schneider ATS22 is NOT Suitable

• For severe heavy-duty starting duties (e.g., heavily loaded ball mills or heavy crushers) — select the heavy-duty Schneider ATS48 range.
• In modern facilities requiring IoT Industry 4.0 compatibility and advanced cyber security — upgrade to the new Schneider ATS480.

Our Field Commissioning Experience

The Altistart 22 series represents an absolute B2B workhorse for water municipal stations. We have installed hundreds of these units in water distribution sites. The integrated bypass contactor saves significant cabinet space, as it prevents continuous heat generation. Remember to configure the thermal overload current setting (parameter `In`) before primary startup.
