Sefuse Sf240e 250V 10A 240c Jet Thermal Temperature Cutoff Fuse
Product descriptions:
Thermal fuse is a kind of non reset type thermal protection device, used for household
appliances and industrial equipment(resistance, inductance circuit) overheating protection,
when the ambient temperature rises to a certain degree, the thermal fuse feels the external
temperature state, and the circuit is cut off.Its fully sealed structure ensures that the system
is stable and reliable, and it is not affected by the harsh environment.
The RY type thermal fuse is equipped with a movable electrode, an arrow and a thermal frit in
its outer shell. Spring B is installed in a compressed state, and its elastic force can resist the
movable electrode with the help of a copper gasket to keep it in contact with lead A. In the state
before fusing, the current is conducted through lead A, movable electric plate, metal shell and
lead B. When the ambient temperature exceeds the operating temperature, the heat introduced
through the leads and metal shell melts the thermal frit into liquid. At this time, spring A and spring
B pop up and stretch. The elastic force of spring A pushes the movable electrode to the side of spring
B, thus cutting off the contact with lead A and thus cutting off the circuit.
