  Explain

 Lead wire: Lead only plays both ends an electrode and the role of the electrical properties of

 product can't afford function decomposition

  

Ceramic tube:To plays fixed and support  

  

End cap: With 58% ~ 62% of brass for base, and nickel plating to prevent oxidation

 

Fuse elements: The key parts of the decided to fuse current specifications

 

1.    Marking

 

     The products lable in two end cap ,cap A and cap B, for the following schedule

 

For example

 

Cap A: Rated current+Rated volltage

                     (100mA~10A) A

    Cap B:Type+manufacture’s logo+ Approved Symbol(optional)

                      cURus 350V

 

   The size of the words not defined,and must be very easy to read.

   

     There shall not be any remarkable stain, rust or crack on the appearances.

 

2.    Part of Testing

 

  5.1  Mechanical  characteristics

 

A.     Tensile Test

 

When fuse is fixed and the tensile force 5N is applied in direction to lend.After the test, there shall be no remarkable damage to the fuses.

 

B.    Thrust Test

When fuse is fixed and the thrust 2N is applied in direction to lend.After the test, there shall be no remarkable damage to the fuses

   

C.Bending Test

 

   Test Condition: Force 5N is applied; number of bends shall be one.After the test, there shall be no remarkable damage to the fuses.

 

2.2           Electrical characteristics

 

         All tests are in the environment temperature 25 ± 5 ℃; Relative humidity45%~75%

 

5.2.1  Over load test

 

When the current in the following table is passing the fuse, its opening time must be in accordance with the requirements in the following table, that is, the pre-arcing time. Moreover, neither damage of the fuse-tube nor shattering of the cap shall occur.

5.2.2  Breaking capacity test

 

  Rated breaking capacity:And after this test, there should be no damage of the fuse-tube or shattering of the caps. After this test, the insulation resistance between the end caps shall be not less than 0.1MΩ.

 

            350V:Rated AC 100A

 

  5.2.3 Temperature rising

 

       At 100% times of rating electric current passes the fuse ,After reaching thermal balance, the temperature on the fuse surface rising is not higher than 75℃.
