ATS01N125FT, ATS01 Series Soft Starter, 11 kW, 25 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: Schneider Electric ATS01N125FT

The Schneider Electric ATS01N125FT is a compact Altistart 01 soft starter rated for 25 A nominal current and a wide supply voltage range of 110–480 V AC (50/60 Hz). It is designed for basic soft start/stop of asynchronous motors and is typically applied to three-phase motor sizes up to about 11 kW (depending on voltage). The unit uses a voltage-ramp start method to limit inrush current and reduce mechanical stress during acceleration, making it suitable for conveyors, pumps, fans, compressors and other simple motor-driven machines that do not require advanced torque control. The ATS01N125FT is DIN-rail mountable, includes an integrated bypass to reduce dissipation during run, and has an IP20 enclosure rating — features that support tight panel layouts and straightforward installation for maintenance and procurement teams.
