1201080246, sometimes referred to as a electric thermal protector, is an thermal protection device used in air conditioners, refrigerators, heating systems, and other electric appliances. It is an important component used to protect the appliance from overheating due to abnormal temperature changes caused by excessive current or other electric fault.

The working principle of the 1201080246 is based on the bimetallic principle. It consists of two different metals that have different coefficients of thermal expansion; when heated, these metals expand at different rates. A metal spring with one end connected to each metal is linked to a contactor. When abnormal temperatures occur, physically twisting the contactor\'s two ends open and activating the circuit breaker.

1201080246 is most commonly used in microwave ovens, heaters, air conditioners, or other electric appliances. In these appliances, the electric thermal protector is usually placed in the electric heating element to monitor the temperature of the heating element to prevent it from overheating. In microwave ovens, the electric thermal protector is used to detect the temperature change in the oven cavity and cut off power if the temperature is too high.

1201080246 are also used in motor-driven equipment to detect and protect them from electrical overload, such as motor, air conditioner, etc. As the motor running, the electric thermal protector can detect whether the temperature generated by the motor is too high or not and it can cut off the power supply when the temperature is too high.

When the 1201080246 is used in a home appliance, it is usually connected to the temperature control switch on the appliance. When the temperature rises, the switch will sense the temperature change, and the mechanical energy driving the switch will cause the internal mechanism to balance the current in the circuit. When the temperature exceeds the set value, it will disconnect the power supply with one-time mechanical action. The temperature control switch will reset to the normal range automatically after the cooling process and restart the power.

It is worth noting that, since the temperature control switch is a one-time mechanical action, when it is used to monitor temperature changes in a given area such as an operating room, for example, it should be reset manually after each cycle. Once the temperature control switch is reset, it will be ready to continue monitoring the temperature in the area.

In conclusion, the 1201080246 is an invaluable thermal protection device used in a variety of electric appliances and motor-driven equipment. Its bimetallic structure and mechanical operation make it robust and efficient in detecting excessive temperatures and cutting off electrical power whenever necessary. Its wide range of applications have made it a must-have in many industries including residential, commercial, and industrial.
