  • Thermistor Trip Relay , when used in conjunction with positive temperature co-efficient thermistors, will help protect against : Sustained overload , Single phasing , Locked rotor , Blocked , ventilation , High ambient temperature . The protector comprises a voltage level detector which detects the voltage across the thermistor. At normal temperature, when the thermistor resistance is low, a command signal energises a Change-Over relay and a green LED showing ‘safe’ condition . At a pre - determined temperature, the thermistor resistance increases rapidly, which de - energises the relay. The actual trip temperature is governed by the thermistor characteristic, which can be obtained from the manufactuer’s data. Other features of this device are : - LED trip indication - 2 pole relay contacts - Auto/Manual reset Bornika is the exclusive agent of Ziegler company in the fields of consultation , sales and distribution of power industry products including Thermistor Trip Relay .
