Introduction

Thermal cut-off device commonly referred to as 240C-TC, which is used in temperature control system in order to prevent overheating and other problems. This device is widely used in electrical and electronic applications. In this article, we will discuss the application field and working principle of the 240C-TC.

Application Field of the 240C-TC

The 240C-TC has wide application in controlling the internal temperature for different kinds of devices. Firstly, the 240C-TC is commonly used in electrical appliances, such as domestic washing machines, dryers, water heaters, air conditioners and so on. By installing the 240C-TC in these electrical appliances, it will automatically shut off when the temperature exceeds the set temperature, thus preventing the electrical appliance from overheating and burning out other components.

The 240C-TC is also widely used in motor vehicle engine control systems. In vehicles, the 240C-TC is usually used to control the coolant temperature. When the engine temperature exceeds the set temperature, the 240C-TC will shut off the power to the engine and cool down the system. This ensures the engine is functioning safely and at the correct temperature.

Working Principle of the 240C-TC

The 240C-TC is made up of two parts, a thermistor and a resistor. When the temperature of an object increases, this will cause the thermistor to rise in resistance. When the resistance reaches a certain level, it will break or make a circuit. Depending on the configuration, the circuit is either broken to open the circuit or made to close the circuit.

When the 240C-TC is in normal working temperature, it will be in the "normally closed" configuration. This means that the circuit is closed and the power is supplied to the device. However, when the temperature of the device exceeds the limit, the thermistor will cause the circuit to be broken, hence opening the circuit and not allowing the current to flow.

Once the temperature has been reduced to the set level, the thermistor will cause the circuit to be made again, thus completing the circuit and allowing the current to flow again.

Conclusion

The 240C-TC is widely used in electrical and electronic applications. It is a thermal cut-off device that is used in temperature control systems in order to prevent overheating. The 240C-TC has a wide application field and its working principle involves the use of a thermistor and a resistor.
