ATS01N222LU, ATS01 Series Soft Starter, 11 kW, 22 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: ATS01N222LU

The Schneider Electric ATS01N222LU is a compact DIN-rail Altistart 01 soft starter rated for 22 A continuous operation and intended for 3-phase supply voltages of 200–240 V AC. It is suitable for motor ratings typically from about 4 kW up to 5.5 kW (approx. 5–7.5 hp) at 200–240 V, making it a practical choice for small to medium machines such as pumps, fans, compressors, conveyor drives and automated doors where simple soft starting is required. The unit uses a voltage-ramp start method with an adjustable start/stop ramp (commonly 1 to 10 s) and provides an integrated electronic bypass to reduce heat dissipation and audible noise after starting. Physically slim (≈45 mm wide) and DIN-rail mountable, the ATS01N222LU is designed for straightforward installation and basic on-site configuration with a small number of settings and discrete control inputs for start/stop and boost functions.
