Specification: Item Type: Thermal Fuse Temperature Range: TF 72 ℃ -250 ℃ (optional) Voltage Current: AC 250V 10A Package List: 10 x Thermal Fuse 192. The thermal fuse is a disposable component connected to the circuit that uses a very precise and reliable temperature to protect the circuit. When the current on the circuit is too high, the heat-sensitive part produces a high temperature and melts, causing the current to be interrupted by an open circuit to protect the circuit from damage. Thermal Fuse 192 can detect abnormal temperature rise in household or industrial electrical products and cut off the circuit quickly and in time to prevent fires. It is an ideal replacement for the melted thermal fuse.
