ATS01N112FT, ATS01 Series Soft Starter, 5,5 kW, 12 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 ATS01N112FT

The Schneider Electric ATS01N112FT is a compact ATS01-series motor soft starter with a rated operational current of 12 A and a wide supply voltage range (nominally 110…480 V). It is sized for small to medium asynchronous motors — typical in-line motor ratings quoted for this model include approximately 1.5 kW for single-phase 230 V motors, 2.2 kW for three-phase 230 V motors and up to 5.5 kW for three-phase 400 V motors (manufacturer power-range groupings also list 1.1–2 kW at 200–240 V 1‑phase, 2.2–3 kW at 200–240 V 3‑phase and 4–6 kW at 380–440 V 3‑phase). The device uses a voltage-ramp soft start (start with voltage ramp) with adjustable starting time (1 to 5 s) to limit inrush current and reduce mechanical stress during acceleration. The ATS01N112FT includes an internal bypass to reduce heat dissipation once the motor reaches speed and is designed for simple machine applications — pumps, fans and compressors — where basic soft starting and low-configuration operation are required. It is a compact, IP20-protected unit with no integrated motor overload relay, and it accepts common control supply voltages (control supply options include 110–240 V AC and 24 V DC as specified by Schneider Electric).
