A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
Ptc Thermistor Wiring Diagram. When the thermistor is mounted there must not be any foreign body between the electrode of the thermistor and the clamping contact. When ptc thermistors are encapsulated with sealing material the precautions given in chapter mounting instructions sealing and potting must be observed. The thermistor is electrically between the contacts of the relay in parallel with the relay contacts.

A thermistor is a type of resistor whose resistance is dependent on temperature more so than in standard resistors the word is a combination of thermal and resistor thermistors are widely used as inrush current limiters temperature sensors negative temperature coefficient or ntc type typically self resetting overcurrent protectors and self regulating heating elements positive. The thermistor is a solid state temperature sensing device which acts a bit like an electrical resistor but is temperature sensitive. The thermistor is electrically between the contacts of the relay in parallel with the relay contacts. The thermistor temperature sensing system consists of positive temperature coefficient sensors ptc embedded in series of three one between each phase and a matched solid state electronic switch in an enclosed control module.
Ptcsl03 ptc thermistor datasheet.
Because you aren t getting a dead short on any test you either have a bad relay or you aren t testing properly. When ptc thermistors are encapsulated with sealing material the precautions given in chapter mounting instructions sealing and potting must be observed. When the thermistor is mounted there must not be any foreign body between the electrode of the thermistor and the clamping contact. Ptc means positive temperature coefficient thermistor however we can called starting relay or compressor starting relay in simple words. The thermistor is a solid state temperature sensing device which acts a bit like an electrical resistor but is temperature sensitive.
Ptc Thermistor Wiring Diagram. Ptcsl03 ptc thermistor datasheet. How a refrigerator ptc relay working and function in the refrigerator compressor we use the split phase single phase induction motor and this motor have internal two types of winding which we called running.
