LT3SE00M, Schneider Electric Thermistor Protection Unit

Schneider Electric TeSys LT3 -S Thermistor Protection Relays.

From Schneider Electric this is the TeSys LT3-S range of Thermistor protection relays designed as an intelligent relay with built-in machine temperature control providing quick and easy selection. The thermistor protection relays can be used with all motors equipped with thermistor probes allowing you to monitor windings temperature, so you do not exceed the rated operating value. This guards the relay against any faults plus can also monitor the surface temperature.
