Temperature fuse


Temperature fuses, also known as thermal fuses (National Standard GB9816.1-2013), are temperature sensing circuit interruption devices. Temperature fuses can sense overheating caused by abnormal operation of electrical and electronic products, thereby cutting off the circuit to prevent the occurrence of fire. Commonly used in: hair dryers, electric irons, rice cookers, electric stoves, transformers, motors, water dispensers, coffee pots, etc...

KSD Temperature Controller Series


When the appliance is functioning normally, the bimetallic strip is in a free state, and the contacts are in a closed/open state. When the temperature reaches the action temperature, the bimetallic strip generates internal stress due to heating and quickly acts to open/close the contacts, cutting off/connecting the circuit, thus playing a role in temperature control. When the appliance cools down to the reset temperature, the contacts automatically close/open, restoring the normal working state.

What is a temperature fuse

Temperature fuses, also known as thermal fuses or thermal melt fuses, are safety devices used to protect circuits or equipment. They are specially designed resistance wires that can automatically disconnect the circuit based on the magnitude of the current and the duration of time, serving the purpose of overload protection.

The working principle of temperature fuses

When current flows through a conductor, the conductor will heat up due to its certain resistance. The amount of heat generated follows this formula: Q=0.24I2RT; where Q is the amount of heat generated, 0.24 is a constant, I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time the current flows through the conductor; from this formula, we can easily see the simple working principle of a fuse.

What is used to sense temperature in a temperature control switch?

Many friends are very interested in what temperature sensing the snap-action temperature control switch relies on! Since it is a snap-action temperature control switch, it must have its own temperature sensing system. Without a good temperature sensing system, it is impossible to predict the temperature.
