ATS01N209QN, ATS01 Series Soft Starter, 4 kW, 9 A, 380 to 415V 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 ATS01N209QN

The Schneider Electric ATS01N209QN is a compact Altistart 01 soft starter rated for 9 A nominal current and intended for three-phase supply voltages in the 380–415 V class. It is specified for motors up to 4 kW (at 400 V) and delivers a voltage-ramp start/stop method with adjustable ramp and deceleration times (1 to 10 s). The unit provides reduced starting current and torque control in the range of approximately 30–80% of direct-on-line torque, making it suitable for light-duty industrial machines such as pumps, fans, small compressors, conveyors, automatic doors and other simple motor-driven systems. Key verified characteristics include an integrated bypass to reduce dissipation once the motor is at full speed, DIN-rail/panel friendly compact form factor (45 mm width), and IP20 enclosure rating — attributes that simplify installation in confined control panels and OEM assemblies.
