S801+N37N3S Eaton Soft Starter

The Eaton S801+N37N3S soft starter belongs to the S801+ series and is built for three-phase motor starting and stopping. Its 37A current rating, N-frame construction, and NEMA 0 rating suit compact installations and retrofit applications. The operating range is 200–600 V at 47–63 Hz, while a 24 V power supply supports the unit’s control functions. Modbus RTU communication is provided through the CIM (Communication Interface Module), and the LCD display allows configuration and monitoring. Control terminals accept 1–2 conductors sized #22–14 AWG. Built-in overload protection and advanced motor protection support fractional horsepower and larger three-phase motor applications. The S801+N37N3S combines motor control, communication, and protection in a compact soft starter format for new installations or retrofits.
