ATS480C66Y, ATS480 Series Soft Starter, 355 kW, 660 A, 208 to 690V AC

Schneider Electric ATS480 Soft Starter Series – Overview

Schneider Electric ATS480 soft starters are advanced motor control solutions designed to deliver smooth, controlled starting and stopping of asynchronous motors in demanding industrial environments. The ATS480 series focuses on reducing mechanical stress, limiting inrush current, and improving overall system reliability through intelligent control and integrated motor protection features. With robust design, advanced diagnostics, and flexible communication options, Schneider ATS480 soft starters are well suited for applications such as pumps, fans, compressors, conveyors, and process machinery. The ATS480 series supports energy-efficient motor operation while enhancing equipment lifespan and process stability across a wide range of industrial sectors.

Product Description: ATS480C66Y

The Schneider Electric ATS480C66Y is a heavy‑duty Altivar ATS480 soft starter with a rated operational current of 660 A (normal duty) and 590 A (heavy duty at 40 °C). It accepts a wide supply voltage range of 208–690 V AC (50/60 Hz) and is suitable for large asynchronous motors from approximately 160 kW up to 630 kW depending on the supply voltage and duty (examples: 355 kW @ 400 V normal duty; 315 kW @ 400 V heavy duty; 630 kW @ 660 V normal duty). Designed for process and infrastructure applications, the ATS480C66Y provides torque control (TCS) for managed acceleration/deceleration and includes dynamic braking and DC injection functions for stopping high‑inertia loads. The unit is intended for in‑line or delta connection to reduce operational current and is built for industrial commissioning with embedded test routines and modular communication options for fieldbus and Ethernet networks.
