Temperature monitor, E3TF01 230V AC

​The TELE E3TF01 is a temperature monitoring relay designed to protect motor windings from overheating by utilizing PTC thermistors. Operating with a supply voltage of 230V AC, it can monitor up to six PTC sensors connected in series, in accordance with DIN 44081 standards. The device features a fault latch for temperature sensors and offers optional short circuit monitoring of the thermistor circuit, selectable via terminals. An integrated test/reset button allows for manual system checks and fault resets. The relay includes one changeover contact rated at 250V AC and 5A, providing reliable switching capabilities. Its compact 35mm DIN-rail mountable design facilitates easy installation in control panels. LED indicators provide clear visual status updates: a green LED indicates the presence of supply voltage, while a red LED signals fault conditions. Engineered for precision and durability, the E3TF01 is an ideal solution for safeguarding motors and other heat-sensitive equipment against overtemperature conditions. - Monitoring relays ENYA series - Motor temperature monitoring - Evaluation of PTC resistors or thermal contacts - Test function with reset button - Supply voltage 230V AC - 1 changeover contact - width 35mm - installation type
