Product Item: SET Square TCO Thermal Fuse Manufacturer
Category: Temperature fuse
Features: Radial and square thermal fuse, thermal cut-off (transparent shell)
A piece of fusible alloy wire is connected between the two pins of the thermal fuse, which is covered by a special transparent resin square shell. Current can flow from one pin to another. When the temperature around the thermal fuse rises to its set operating temperature, its fusible alloy wire melts and shrinks into a spherical shape, and is attached to the ends of the two pins with the help of surface tension and special resin. In this way, the circuit is permanently cut off.
