RY type temperature fuse


RY type thermal fuse is the use of metal shell, with temperature sensitive particles (organic chemicals) as a thermal fuse. Since the structure of the temperature sensitive material is not energized, the internal impedance is small and the cut-off current is as large as 6A-15A(AC).

RH type temperature fuse


When the temperature around the RH thermal fuse rises to its operating temperature, its fusible alloy melts under the help of surface tension and special resin, and the fusible alloy wire breaks and shrinks into a spherical shape attached to the end of the two pins. In this way, the circuit is permanently cut off.
