Ptc Thermistor Circuit Diagram. Ceramic ptc thermistors are a replacement to conventional fuses to protect loads such as motors transformers etc. Thus changes to its resistance due to changes in temperature produces a temperature related output voltage.
These ptc thermistors are used a switch in motor starting circuits degaussing circuits etc. The socket side includes a ptc thermistor for overcurrent protection. Tdk offers a comprehensive lineup of ptc thermistors for telecom applications.
Used in three phase motors.
The thermistor is temperature sensitive resistor whose resistance modifies as per the temperature. The diagram below shows an example of a protection circuit that uses a replaceable plug in spd. Ptc thermistor as fuse. Tdk offers a comprehensive lineup of ptc thermistors for telecom applications.
