S811+V50V3S Eaton Soft Starter

The Eaton S811+V50V3S is a soft starter intended for three-phase motor starting and rated pump control applications. Its 500 A current rating and 690 V voltage rating position it for high-capacity industrial equipment, while the pump-control function supports smooth motor acceleration and deceleration. This approach helps reduce mechanical stress and limit water-hammer effects during controlled starts and stops. The unit uses a 290 mm frame size for installation in demanding industrial environments. As a member of the S811+ intelligent soft starter family, the S811+V50V3S also provides advanced motor protection and is applicable to retrofit projects and new industrial installations.
