S811+V72V3S Eaton Soft Starter

This Eaton S811+V72V3S intelligent soft starter provides controlled starting and stopping for three-phase motors in Delta (3-lead) configurations. Rated at 720A and 690V, the S811+ unit is suitable for motors from fractional horsepower through 1000 amps steady-state current. Its compact 290 mm frame suits retrofit applications involving existing motor control centers, wye-delta starters, and across-the-line NEMA or IEC starters. Rated Pump Control targets pumping systems, while smooth soft stopping helps reduce water hammer effects that can damage pipes, valves, and pumps. Built-in overload protection spans 12–1000 amps, and the integrated run bypass contactor simplifies installation and setup. This 3P device combines motor control, overload protection, and the S811+ series’ compact footprint for industrial motor applications.
