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℃. |
