ATS480D75Y, ATS480 Series Soft Starter, 37 kW, 75 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 ATS480D75Y

The Schneider Electric ATS480D75Y is an ATS480-series soft starter rated for 75 A (normal duty) and designed for three-phase supply voltages from 208 V to 690 V. Depending on supply voltage and wiring (inline or delta), this model covers a wide motor power range — commonly specified as 18.5 kW at 230 V (inline normal duty) up to 55 kW at 400–690 V when connected in the motor delta (normal duty). The ATS480D75Y provides torque control (TCS) for controlled acceleration and deceleration, and includes motor overload protection. It supports dynamic braking and DC injection for stopping high-inertia loads and can be installed inline or wired to the motor delta to reduce operational current. With IP20 protection and conformity to IEC/EN 60947-4-1, the ATS480D75Y is intended for process and infrastructure applications such as pumps, compressors, conveyors and other industrial motor loads that require reduced mechanical stress, limited inrush, and enhanced start/stop control.
