1.Each thermal fuse has a rated current and voltage, a melting temperature , an operating temperature, and a maximum temperature and should be used under the specified parameters.

2.When selecting the fuse installation location, be careful not to shift the stress to the fuse due to vibration and other parts of the finished product.

3.Install in a place where the temperature will not rise above the maximum operating temperature after the thermal cutoff is blown.

4.It should not be used for liquid or in a machine where the humidity is maintained at 95% or more.

5.Install the thermal fuse in a place where only the heat source of the thermal fuse can be sensed. If it is unavoidable to set up a thermal barrier in the structure, for example, when it is installed in the heater, it is necessary to pay attention that it cannot be directly connected so that the hot wire will not be heated to the thermal cutoff.

6.If the thermal fuses are connected in parallel to increase the current flow of the thermal fuses, or if they are continuously subjected to over-current or over-voltage, the internal contacts of the thermal fuses will be damaged, and the normal operation of the thermal fuses will be affected, and they should not be used in the above conditions.

Although thermal fuses are designed to be highly reliable, there is a limit to the number of abnormalities that can be handled by a single thermal fuse. If the thermal fuse is damaged and fails to function properly due to man-made or unforeseen force majeure, it will not be possible to cut off the circuit in time when an abnormality occurs in the machine. Therefore, in the event of overheating of the machine, in the event of faulty operation that directly affects the human body, in the event that there is no circuit to cut off the equipment other than the fuse, and in the event that a high degree of safety is required, it is necessary to use two or more thermal fuses that have different melting temperatures.
