[Construction - Section 109]

An electric fuse, or melting fuse, an overcurrent protection device with a circuit for high amperage to the thermal effect of the flow interrupted, thereby destroying itself.
Also use the circuit breakers and used as a protective element of PTC and temperature switches as a backup.

They are always a insulating body, the two by a melting conductor associated electrical contacts or wire connectors entered.
The director will melt it flowing through the current heated and melted when the rated current of securing significantly exceeded. In this case the backup unfit and security must be replaced by a new.

The melting head, usually from electrolytic copper or fine silver produced by air or quartz sand as arc-extinguishing surrounded. Silica sand is necessary for the arc to erase when interrupting the specified turning off electricity created several orders of magnitude higher than the response can be. The head through melting of response during the three states that are solid, liquid and gaseous.

In the gaseous state of the melting head, a plasma, the current flow through this and it forms an electric arc. This is reflected in the metal melting head of steam on the surface of the quartz sand grains down and then the arc from cooled. As a result, the resistance inside the protective rate so high that the level of recurrent tension is not enough, the stream flow re-establish or the arc again to ignite. The arc extinguished and the line is to be protected so that differs from the power source.
