what is a ptc relay used for quizlet

E.g Example: If you start your fridge and then you switch off and then start it, you will note that the compressor does not start again because of the heat thermistor or relay. True In the PTC relay the supply goes direct to the run winding but between the supply and start winding a thermistor is connected in series and when we switch on the refrigerator the current start flowing through the thermistor to the auxiliary and compressor start-up, this current flows heat thermistor and due to temperature, the resistance of Micro relays are more compact than the standard size and are an ideal choice when you need to save space - for example in an ATM fuse box set up with mini fuses.

It controls the opening and closing of the circuit contacts of an electronic circuit. Used in conjunction with respective PTC thermistors they provide a reliable temperature protection in the temperature range 60 C up to 180 C. During operation, the compressor motor will rotate in the opposite direction to change the direction of refrigerant flow. The PTC relay, the power is supplied directly to the running coil, but between the supply reel and starting from a thermistor it is connected in series and the start cooling start of the current passing through the thermistor to start the auxiliary and the compressor due to the temperature resistance of the large thermistor thermistor eliminates the starting winding of the supply.
