STRUCTURE AND FEATURES

• CONTACT HEADS

Contact caps at the ends of the body are made of suitable copper material. Contact heads are designed to withstand excessive pressure, mechanical and sealing stresses inside the fuse due to the arc. Copper contacts can be plated with nickel or silver in terms of conductivity and life.

•  EXTERNAL BODY

The insulated pipe surrounding the outer body is made of ceramic material, and they are materials that can withstand thermal stresses that can cause rapid temperature increases, electrical stresses that may occur after fractures, and mechanical stresses that may occur due to pressure on the inside. Their surfaces are glazed and shiny and they are protected from water, moisture, steam etc. It is not affected by atmospheric conditions and does not hold dust and dirt in terms of its external structure.

•  CARRIER

 It is made of ceramic material. It prevents direct contact with the body by damping the mechanical stresses that may arise from the control wire during short circuit. It is placed in the inner part of the pipe surrounding the outer body and it is a material with a perforated structure inside. The melting wire is wrapped around the outside and the control element wire is passed through the inside.

• MELTING LINE

This part is the main material of the fuse. Silver wire with high purity, precise dimensions and very small resistance is used as an ideal melting line in fuses. The silver wire used in the melting line is determined by careful observation of the results of the tests that meet the necessary criteria of different types of fuses.

• EXTINGUISHING SAND

The extinguishing material is 99.8% pure quartz sand and this material should be sieved and free from moisture. Thanks to this special sand, the electrical conductivity that occurs during the arc that may occur due to current in the fuse and the high temperature caused by high current in the melting line can be damped.

•   INDICATOR ELEMENT

 The indicator element is a mechanical device that indicates correct fuse action. In case the melting wire inside the fuse melts or burns, it transmits the electric current through the control wire and enables the indicator element to blow. The control wire does not cause early tripping of the indicator element or any adverse effect on the cutting process.
