ATS480M12Y, ATS480 Series Soft Starter, 630 kW, 1200 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: Schneider Electric ATS480M12Y

The Schneider Electric ATS480M12Y is an ATS480-series soft starter with a rated operational current of 1200 A, designed for three-phase supply voltages from 208 V to 690 V AC. It supports large asynchronous motors and is specified to control motor power up to the hundreds of kilowatts range: typical verified ratings for this frame include standard connection motor powers of approximately 355 kW at 230 V and 630 kW at 400 V, with higher triangle/delta-connection ratings reported (for example up to 500 kW in delta at 230 V and ~680 kW in delta at 400 V). The unit implements Schneider’s torque control (TCS) and standard soft-start voltage ramp strategies to manage acceleration and deceleration, and includes integrated motor overload protection. ATS480M12Y is built for heavy industrial uses — process lines, pumps, compressors, conveyors and large rotating equipment — where limiting inrush current, reducing mechanical stress, and providing controlled stopping (including dynamic braking and DC injection features reported for the series) are required. Communication options and modular interface support enable integration into industrial automation systems.
