Schneider Electric ATS48D17AA Soft Starter Module

Schneider Electric Altistart 48 soft starter module ATS48D17AA is a panel-mounted device that provides controlled soft starting and stopping for asynchronous motors, rapidly reducing inrush current and minimizing mechanical stress on drive trains during acceleration and deceleration, which helps protect connected pumps, fans, and conveyors. Designed for three-phase supply lines from 208 to 690 VAC and 50/60 Hz operation, the D17 variant carries a nominal current rating of 17 A, enabling it to handle motor loads in that range across multiple voltage configurations. The unit accepts a control supply of 110 to 230 VAC, allowing straightforward integration with common plant controls and PLCs. As part of the Altistart 48 family, ATS48D17AA is commonly applied in pumping and ventilation equipment and other standard industrial processes where a smooth ramp-up and ramp-down of motor speed improves equipment life and minimizes electrical disturbances.
