ATS480C11Y, ATS480 Series Soft Starter, 55 kW, 110 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: ATS480C11Y

The Schneider Electric ATS480C11Y is an ATS480-series soft starter rated for 110 A (normal duty) and designed for three-phase motor supplies from 208 V to 690 V AC. Depending on supply voltage it covers motors from approximately 30 kW up to 90 kW in-line (values vary with mains voltage and duty); heavy-duty rated current for the unit is 88 A. The ATS480C11Y uses Schneider’s torque control (TCS) algorithm to manage acceleration and deceleration, and includes functions for dynamic braking and DC injection for efficient stopping of high-inertia loads. Built for industrial process and infrastructure applications, this unit is intended where controlled, repeatable industrial motor starting and stopping is required while reducing mechanical stress and limiting inrush current. The product is supplied with a 110…230 V control supply and is designed to integrate with optional communication modules for fieldbus and Ethernet networks.
