Schneider Electric ATS490M10Y Altivar ATS490 1000 A 208-690V 3-Phase 500 kW Soft Starter
Schneider Electric ATS490M10Y Altivar ATS490 soft starter, 1000 A normal duty (up to 500 kW at 400V), 208-690V AC supply, integrated STO.
Description
About the ATS490
About the ATS490
The Schneider Electric ATS490M10Y is a soft starter from the Altivar Soft Starter ATS490 range, built to ramp asynchronous motors smoothly from a 208-690 V AC supply. In normal duty it carries 1000 A continuous (790 A in heavy duty) and drives up to 500 kW at 400 V. It integrates Safe Torque Off, native Modbus TCP/EtherNet/IP, and IP00 protection for enclosure mounting.

Selection Notes
The 1000 A normal-duty rating covers motors up to 500 kW at 400 V; where the load runs a more demanding duty cycle, the heavy-duty curve drops to 790 A for motors up to 400 kW. The 400% Ie for 13 s overload profile sets how long the starter tolerates a stalled or jammed load before tripping, relevant when sizing against pump or conveyor startup torque. The integrated Safe Torque Off input meets SIL 1 / PL c without an external safety contactor on the motor branch. As an IP00 frame, the ATS490M10Y ships without a plastic enclosure and is intended for installation inside a dedicated switchgear cabinet rather than direct panel mounting.
Applications
The ATS490 range targets pumps, fans, compressors, conveyors, mixers, cutters, grinders, and crushers where a controlled, torque-limited start reduces mechanical and electrical stress at startup.
