EATON S811+N37N3L Soft Starter Reduced Voltage Motor Starters Solid-State Starters

S811/S811+ Series

The S811/S811+ line of Intelligent Technologies Soft Starters is designed to be the smallest, most compact soft starter in the market today. 

With this small size, it can easily fit in place of existing soft starter designs, wye-delta starters or across-the-line 

NEMA and IEC starters. This feature allows easy retrofits of existing Motor Control Centers or Enclosures and saves 

the expense of replacing existing structures or adding a new one to house a soft starter. 

The product is designed to work with 3-phase motors in a Delta (3-lead) configuration. 

The S811/S811+ works with all motors from fractional horsepower up to motors requiring 1000 amps of steady state current. 

The built-in over-load (in ranges from 12 - 1000 amps) and run bypass contactor make installation and setup quick and easy. 

The overload also offers some advanced protective functions to give additional motor protection. 

With the pump control option, it is the number one soft starter available for pumping applications. 

The unique soft stopping control provides a smooth transition for stopping a motor and eliminating 

the "water-hammer" effect that can damage pipes, valves, and pumps.

Features

• Unique soft stopping pump control option provides a smooth transition for stopping a motor and

  eliminates the "waterhammer" effect that can damage pipes, valves and pumps

• Advanced protective and diagnostic features using sophisticated algorithms that model true motor heating,

  result in better motor protection and fewer nuisance trips, reducing downtime

• Compact size allows easy retrofits of existing motor control centers or enclosures, and saves the expense of replacing

  the existing structure or adding a new one to house a soft starter

• Easy to use Digital Interface Module (DIM) allows the user to configure the device and to read system parameters and monitor system values

• Built-in overload (in ranges from 11–1000A) and run bypass contactor make installation and setup quick and easy

• Reduced inrush current leads to a more stable power grid and can lower peak demand charges
