Schneider Electric ATS430 Soft Starters — Specialized Range for Heavy Water and Mining Processes

The Schneider Electric Altistart 430 (ATS430) soft starter series is a highly specialized, process-oriented solution engineered for critical pumping and minerals B2B applications, covering capacities from 15 to 315 kW. It integrates symmetrical three-phase thyristor control with advanced torque-limiting algorithms. The ATS430 is designed for energy-efficient panel designs, supporting Inside-Delta wiring configurations to minimize terminal current limits and enclosure footprints.

Typical Applications for Schneider ATS430

• High-Head Submersible Pumps and Large Lift Stations: Advanced water stopping curves protect deep well column pipes and eliminate water hammer.
• Heavy Agitators and High-Viscosity Homogenizers: Dynamic torque compensation helps start viscous fluids without tripping thyristors.
• Mid-Size Industrial Crushers: High starting thermal capability sustains heavy current-limited start cycles.

What Differentiates Schneider ATS430 from Competitors

Featuring Class 30 heavy-duty thermal overload curves, the ATS430 can sustain prolonged startup cycles in heavy mechanical machinery without causing premature tripping.

When Schneider ATS430 is NOT Suitable

• For simple, lower-power HVAC fans where advanced B2B process tuning is not required — select the Schneider ATS01 or ATS22.
• In plants requiring dynamic, continuous motor speed adjustment across the process.

Our System Engineering Experience

The ATS430 represents an excellent choice for confined mechanical rooms. Integrated ground fault safety and thyristor thermal modeling guarantee a long service life. Always configure the deceleration profile parameters to match the hydraulic characteristics of your pump system.
