ATS01N103FT, ATS01 Series Soft Starter, 1,1 kW, 3 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 ATS01N103FT

The Schneider Electric ATS01N103FT is a compact DIN-rail soft starter rated for 3 A and intended for straightforward industrial motor starting tasks. It supports a wide supply voltage range (nominally 110–480 V AC and with verified limits of approximately 99–528 V) and is suitable for small asynchronous motors: verified motor power ratings include approximately 0.37 kW for single-phase 230 V motors, 0.55 kW (three-phase) at around 230 V and up to 1.1 kW (three-phase) at around 400 V. The unit uses a voltage-ramp (phase-angle) control method to limit inrush current and reduce mechanical stress during acceleration. ATS01N103FT includes an integrated bypass contact and is intended for simple machines such as pumps, fans, compressors, conveyors and automatic doors where basic soft starting (no advanced torque or multi-step control) is required. Key practical advantages are its very small 22.5 mm width for tight control panels, simple two‑setting configuration for quick commissioning, and IP20 enclosure for panel mounting.
