Schneider Electric ATS48 Soft Starters — The Legendary Heavy-Duty Industrial Range
The Schneider Electric Altistart 48 (ATS48) soft starter series is a true global legend in heavy industrial automation, designed to handle extreme starting profiles for electric motors from 7.5 to 630 kW. The core of the ATS48 is its patented TCS (Torque Control System) algorithm, which maintains a completely linear acceleration profile regardless of shaft mechanical torque fluctuations. This provides high-end, fully symmetrical three-phase control capable of sustaining heavy thermal loads.
Typical Applications for Schneider ATS48
Heavy-Duty Mills and Stone Crushers: Symmetrical three-phase thyristors easily handle starting currents of up to 500% of nominal rating for 30 seconds.
High-Inertia Ventilation Impellers: Delivers smooth, controlled starting ramps for massive exhaust fans without generating excessive winding heat.
High-Pressure Municipal Water Pumps: Active TCS torque control manages fluid deceleration profiles, protecting pipes from checking pressure waves.

A primary structural design element of the ATS48 is its large, heavy-duty external heatsink. By omitting a built-in bypass contactor, the chassis serves as a massive thermal radiator for demanding cycles.
When Schneider ATS48 is NOT Suitable
For basic starting tasks where panel space constraints require an integrated, compact bypass design — select Schneider ATS22.
For B2B facilities modernizing process layouts and demanding native cyber-secured IoT connectivity — upgrade to the next-gen Schneider ATS480.
Our System Assembly Recommendations
The Altistart 48 is exceptionally robust and durable. Many B2B systems we have deployed have operated in mining and wood-processing environments for over a decade. When designing panel schematics, always specify an external bypass contactor wired in parallel. This unloads the thyristors during run state, saving energy and eliminating cabinet thermal buildup.
Давно працюємо з обладнанням Schneider Electric, і цей софтстартер ATS48 на 1000А не став винятком. Ставили його на великий компресорний агрегат, де пускові струми були просто шалені. Після монтажу одразу відчули різницю – плавний пуск, без тих диких ривків, що раніше були. Для такої потужності це серйозно допомагає зберегти механіку і мережу не навантажувати зайвий раз. Монтаж пройшов норм, все чітко підключили. Знаємо, що Schneider дорожчий за деякі аналоги, але його надійність і ресурс того варті, особливо на таких відповідальних ділянках. Працює стабільно, без нарікань.
