What Is A Fuse?
Fuses are also known as current fuses, and the IEC127 standard defines  it as a "fuse body." It is primarily a function of current overload  protection. When the circuit fails or abnormal, accompanied by rising  current, and the rising current may damage some important devices in the  circuit, it is possible to burn the circuit or even cause a fire.
If the circuit correctly install the fuse, then the fuse will rise in  the current to a certain height and heat, when the fuse itself cut off the current, so as to protect the safe operation of the circuit.

Fuse Characteristics
• Resistivity is large; low melting point.
• Small size, easy to install
• Disjunction capability precision, reliability
• Different structural features, installation in various forms
• Under normal conditions, the fuse has a long shelf life
• Recoverable fuse, reset can be repeated use
• Long life of the fuse, in case of fault-free circuit, synchronized with the life of the equipment


Working Principle
Current fuse  is a hot fusing working principle, when the current flows through the  conductor, because fusing wire conductor there is a certain resistance,  so the conductor will heat up. When the circuit current is not normal  rise,fusing wire will heat fusing, cut off the circuit current.
Resettable fuse is a current anomaly, the resistance becomes larger working principle,  when the current through the polymer polymer is not normal rise, the  fuse resistance will become larger, through the fuse current will be  reduced to ensure the normal work of the circuit.
