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.
Advantages
• Precise repeatability of the response point.
• Long hysteresis free switch cycle life.
• Extremely cost effective.
• Steep temperature-resistance curve characteristic allows for simple evaluation electronics.
• Current self-limiting.
• Light weight.
• Low thermal time constant.
• Extremely small designs are available.

Note
1.Insert wire in the winding wire slot of the motor,make it tidy, and then mount the PTC thermistor in the coil of motor(as shown in figure).
2.White mounting,do not hard beat or press the sensing area of the thermistor for fear that the internal precise structure of the product might be damaged.
3. While mounting,do not extremely hard pull the outgoing line of the product for fear that the outgoing line might be pulled apart.
4.Before connecting,read the technical information about PTC temperature control module(the former GRB motor overheat protector) for fear that the thermistor might be damaged.
5.Securely connect the outgoing line in the specified connection position.
