S811+N66N3S Eaton Soft Starter

The Eaton S811+ N66N3S is a soft starter for three-phase motor starting. Its 66 A current rating, N-frame construction, and three-pole configuration define its electrical installation requirements. The unit supports 200–600 V at 47–63 Hz, providing the operating range for compatible three-phase motor control systems. An LCD display supports on-device monitoring, while Modbus RTU communication enables networked control and integration. The 24 V power supply supports advanced monitoring and control functions. For delta (3-lead) three-phase motor applications, the starter includes built-in overload protection and a run bypass contactor to simplify installation. Its compact footprint accommodates retrofits in existing motor control centers, while the S811+ series is suited to demanding starting applications.
