S811N37P3S

The S811N37P3S soft starter is an open soft starter by Eaton Cutler-Hammer. It runs on a voltage range of 200 to 600 Volts AC, with 37 Amps of current. It has a 65-millimeter frame size, a Horsepower rating of 10 Horsepower and an operating frequency range of 47 to 63 Hertz. The starter also comes with standard features and the pump control option. This starter also comes with an insulating voltage of 660 Volts. The Eaton S811N37P3S soft starter is used in AC electrical motors to temporarily decrease the torque and load on the power train as well as the motor’s electric current surge during start-up. The S811 series soft starters have all the critical features of the Eaton S801 soft starters, but they also have improved functionality with the option of the new Digital Interface Module (DIM), metering, communications, monitoring, and diagnostics capabilities. The S811 reduced voltage soft starters by Eaton are multi-functional, very compact, and easy to install and configure. The S811N37P3S soft starter is specially engineered to offer control for both the acceleration and deceleration of the 3-phase motors to an optimum voltage of 690 Volts. Besides, this line of soft starters is accessible with currents of 11 to 1000 Amps.

The S811N37P3S soft starter and all the S811 soft starters are designed as a complete package that merges the silicon controlled rectifiers or SCRs and the overload and bypass contactors into one compact unit. The S811 soft starter series comes as a panel mounting component, or it can be put in motor control centers or in an enclosed control center. Other features of this soft starter include an edge and level sensing control. It also comes with a built-in communication option through the Quick Connect (QC) port that enables connection to many networks. The soft starter has starting modes such as the voltage ramp start as well as the current limit start. The S811 soft starters also have diagnostic capabilities, including fault queue, breaker status, and control status diagnostics. They feature a variety of system protection and monitoring capabilities.
