S811+T30V3S Eaton Soft Starter

The Eaton S811+ is a soft starter configured for motor starting and stopping in demanding pump installations. Its 304 A current rating and 690 V voltage rating suit three-phase industrial motor applications, while rated pump control supports controlled transitions during operation. Soft stopping is designed to limit hydraulic shock and reduce water-hammer effects that may affect connected pumps, piping, and valves. The unit uses a compact 200 mm form factor, making it suitable for retrofit into existing installations where space is limited. The S811+T30V3S model provides a compact solution for applications requiring controlled pump starting and reliable three-phase motor support.
