S811+V72P3S Eaton Soft Starter

The Eaton S811+V72P3S is a compact soft starter for 3-phase motors in Delta (3-lead) configurations, combining controlled starting and stopping with pump-specific functionality. Rated at 720A, its 290 mm size helps minimize panel space requirements. The S811+ series supports motors from fractional horsepower up to 1000 amps steady-state current and includes built-in overload protection across a 12 to 1000 amps range. An integrated run bypass contactor supports simplified installation and setup. The Pump Control option enables smooth soft stopping to eliminate water hammer effects that can damage pipes, valves, and pumps. This unit can be used to retrofit existing motor control centers, wye-delta starters, across-the-line NEMA starters, and IEC starters without requiring structural modifications.
