A: A potentiometer is a manual device to change the resistance A thermistor changes as a function of environment temperature
a device protecting conductors or other equipment in a circuit from an overload/overcurrent situation
A semiconductor device that is particularly sensitive to changes in temperature, permitting it to serve as an accurate measure of temperature.
due to the extension of loads they are using the relays for protection.........
Fuses or circuit breakers are termed 'overcurrent protection devices', which protect circuits from either an overload current or a short-circuit current.
Output
A device with an overload protection used to control a motor is an Overload Relay.

They are a safety mechanism designed to open or break the circuit in the case of overload. They are usually used when a device on the circuit would be damaged or destroyed by an overload.
Wire and a small device called a 'thermistor'
A NTC thermistor is a temperature sensor that has a "negative temperature coefficient". That means as temperature goes up, the resistance of the device goes down over it's operating range.
A: a thermistor will change with temperature so if temperature becomes unsafe its output is monitored and other circuit will shut down the electronics . It can also be used as a controlling device whereby temperature is involved

A thermostat is a device that measures and controls temperature in a system, often used in heating and cooling systems. A thermistor is a type of resistor that changes resistance based on temperature, typically used for temperature sensing or controlling circuits. In summary, a thermostat is used to control temperature, while a thermistor is used to measure temperature.
