Basic information
PTC thermistors are ceramic semi-conductors which because of the very high Positive Temperature Coefficient lend themselves to a variety of applications.
Applications
Specially constructed versions of these products are available and this facility enables most applications to be catered for. Most typical application for PTC thermistors is to protect the windings of heavy duty motors and transformers.
General function
The PTC thermistor, for the thermal protection of electrical machines, is a temperature dependent component. The rated operating temperature (ROT) corresponds to the curie point temperature of the ceramic. The resistance, of the PTC thermistor, rises very steeply with relatively small increases in temperature, thus triggering the switching function.
