Eaton EMT6 Thermistor Motor-Protection Relay, 230 V AC/DC

The Eaton EMT6(230V) is a thermistor motor-protection relay for use with PTC sensors embedded in motor windings, and is suitable for the protection of EEx-e certified motors. It includes a differential trip function to detect sensor circuit faults, with 1 NO + 1 NC output contacts rated up to 230 V and a 23 mm DIN-rail width. Typical applications include hazardous-area motors, pump and fan drives, and general industrial motor protection where direct winding temperature monitoring is required.
