What is the self-recovery fuse:

What is the self-recovery fuse:

Answer:

The use of metal sodium as a melt, at room temperature with high conductivity.

When the circuit occurs short-circuit fault, the short-circuit current to produce high temperature so that the rapid vaporization of sodium, steam sodium showed high resistance,

thus limiting the short-circuit current.

When the short-circuit current disappears, the temperature drops, the metal sodium returns to the original good conductivity.

Since the fuse can only limit the short circuit current, can not really break the circuit. The advantage is that you do not have to change the melt and can reuse it.
