UTP28X41BL is a kind of thermal protection component designed to protect electrical circuits and electric motors by sensing any increased temperature within the motor. This type of thermal protection provides a range of protection against overheating and unwanted operation of the motors because it can cut off power to the motor in the event of any over-temperature situations.

The UTP28X41BL is composed of a ceramic body with internal and external temperature sensing elements, which are used to detect the temperature of the component in different places. There are two resistance elements which have different temperature coefficients, and these are used to measure the temperature difference of two opposite points. The output voltage change is proportional to the temperature difference, and this output voltage is processed by a microprocessor, which can then cut off the power supply of the motor.

The application fields of the UTP28X41BL includes motor protection, electric machinery protection, air conditioning fan protection, transformer and other equipment. Motor protection is the most common application, as it can protect the motor from being damaged due to temperature rise. The UTP28X41BL could cut off the power supply of the motor and prevent it from operating at higher than normal temperatures.

The working principle of the UTP28X41BL is based on the measurement of two different temperature coefficients. The temperature difference between the internal and external sensing elements is converted to an output voltage with the proportional of 13mV or 20mV/℃, depending on the resistance of the components. When the output voltage exceeds the set threshold, the microprocessor cuts off the power supply of the motor.

The UTP28X41BL is a reliable thermal protection component, and with its superior performance, it can significantly improve the reliability of electric motors and prevent them from operating at higher than normal temperatures.
