S811+V85P3S Eaton Soft Starter

The Eaton S811+V85P3S is an intelligent S811+ series soft starter rated at 850 amps for 3-phase motors in Delta (3-lead) configurations. Its compact 290 mm frame suits space-conscious installations and retrofits of motor control centers, wye-delta starters, and across-the-line NEMA or IEC starters. Advanced motor starting and stopping control includes Pump Control with OPT Inside Delta for optimized pumping applications. Soft stopping minimizes water hammer, reducing mechanical stress on pipes, valves, and pumps. Built-in overload protection spans 12 – 1000 amps, while an integrated run bypass contactor simplifies installation and commissioning. The starter supports motors from fractional horsepower through 1000 amps steady-state current for industrial motor-control applications.
