UMI TAM 250V 1A, 2A, 3A, 5A Ceramic Thermal Cutoff Fuse Link
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 (电流保险丝), which melts due to the heat generated when the rated current is exceeded in the circuit.

LEAO, 染料, Panasonic, SWC Limiter thermal fuse
The melt material used in LEAO, 染料, Panasonic, SWC thermal fuses plays a vital role in the performance of thermal fuses and is one of the core components of the entire device. According to the characteristics of the melt material, we can divide them into two categories: low melting point and high melting point.
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.
