A Schneider Electric Soft Starter(in brief) is a motor‑starting device from Schneider’s Altistart family that provides smooth acceleration and deceleration by gradually controlling voltage, reducing inrush current, mechanical stress, and water hammer in pumps.

⚡ Schneider Soft Starter

• A Schneider soft starter controls motor starting and stopping by ramping the voltage up/down.
• Reduces electrical stress, mechanical shock, and starting current.
• Common in pumps, compressors, fans, and conveyors.
• Does not control motor speed during normal running (unlike a VSD).
• Known for reliability, compact size, and built‑in protection(overload, phase loss, thermal).

🔧 Main Schneider Soft Starter Series

• ATS01 — Compact, economical, for small motors.
• ATS22 — Energy‑efficient, with advanced protection.
• ATS480 — Heavy‑duty, digital, for industrial applications.

⭐ One‑line summary

Schneider soft starters give motors a smooth, low‑stress start and stop, improving equipment life and reducing electrical/mechanical wear.
