The self-recovery fuse is composed of specially treated Polymer resin and conductive particles (Carbon Black) distributed in it.Under normal

 

operation, the polymer resin tightly bound the conductive particles outside the crystalline structure to form a chain-like conductive electrical path.

 

At this time, the recoverable fuse is in the state of low resistance (A), and the thermal energy generated by the current flowing through the self-

 

recovering fuse on the line is small and will not change the crystal structure.When the circuit is short-circuited or overloaded, the heat generated

 

by the large current flowing through the self-recovery fuse melts the polymer resin, and the volume grows rapidly, forming a high resistance state

 

(B), and the working current decreases rapidly, thereby limiting and protecting the circuit.When the fault is removed, PTC can restore the fuse

 

cooling crystallization, volume contraction, conductive particles to form a conductive path, the recovery fuse to restore low resistance state, so as

 

to complete the protection of the circuit, without manual replacement.
