أومي تام 250 فولت 1 أمبير, 2أ, 3أ, 5وصلة فيوز للقطع الحراري من السيراميك
UMI TAM temperature fuse is also called thermal fuse. It is a safety overheat protection component. It is generally installed in electrical products that are prone to heat. When the electrical appliance overheats and the temperature exceeds the abnormal temperature, the temperature fuse will automatically melt and cut off the power supply to prevent the electrical appliance from causing a fire. Under normal circumstances, the temperature fuse only serves as a power supply path in the circuit. If it does not exceed its rated value during use, it will not be melted and will not have any effect on the circuit. Only when the electrical product fails or produces abnormal temperature will it be melted to cut off the power circuit. This is different from the current fuse (current fuse), which melts due to the heat generated when the rated current is exceeded in the circuit.

Temperature Rating (Tf):Rated opening temperature
Action Temprature (Ta): Actual measured opening temperature
Holding temperature (Th):Maximum temperature measured at the case end ofthe thermal cutoff at which the thermal cutoff can be maintained for a period for 168 hours without opening.
Maximum temperature (Tm):The maximum temperature at which a thermal cutoff can be maintained for10 minutes as an open circuit and can then be maintained at twice rated voltage for a period of 2 minutes during which its mechanical and electrical properties will not be impaired

thermal fuse and circuit breaker cutoff temperature
They are the same in that they can achieve short circuit protection. The principle of a thermal fuse is to use a current flowing through a conductor to cause the conductor to heat up. When the melting point of the conductor is reached, the conductor is melted so that the circuit-protected electrical appliances and lines are not burned.
