ATS01N109FT, ATS01 Series Soft Starter, 4 kW, 9 A, 230 to 400V AC

Schneider Electric ATS01 Soft Starter Series – Overview

Schneider Electric ATS01 soft starters are compact and cost-effective motor starting solutions designed for basic soft starting of asynchronous motors in standard industrial applications. The ATS01 series focuses on reducing mechanical stress and limiting starting current during motor acceleration, offering a simple and reliable alternative to direct-on-line starting. With a straightforward design and minimal configuration requirements, ATS01 soft starters are well suited for pumps, fans, compressors, and other simple motor-driven machines where basic motor starting control is sufficient.

Product Description: ATS01N109FT

The Schneider Electric ATS01N109FT is a compact Altistart 01 soft starter rated for 9 A nominal operational current, designed for simple industrial motor starting tasks. It accepts a wide supply voltage range from 110 V to 480 V AC and is suitable for inline three-phase motor powers up to approximately 1.5 kW at 230 V and 4 kW at 400 V (motor power ratings depend on wiring and voltage). The unit is DIN-rail or panel mountable (45 mm width), includes an internal bypass contactor to reduce heat dissipation during run, and provides adjustable starting time and torque suppression (starting torque typically adjustable in the 30–80% range). Built for basic motor control use, the ATS01N109FT is a practical choice for small conveyors, pumps, fans, compressors and other simple motor-driven machines where space is limited and a straightforward motor soft starter is required. Confirmed environmental and mechanical specs include IP20 protection, -10 °C to 40 °C operation without derating (with derating above 40 °C), and compliance with EN/IEC 60947-4-2.
