Description:

Glass fuse is an electric element protecting electric devices. It is commonly connected with a circuit in series, and when fault current increases to a certain value, the fuse blows out to cut off the circuit so as to fulfill an aim of protecting other equipment in the circuit. The fuse is the most commonly used component in a over-current protection circuit. The traditional fuse mainly consists of two parts of a tube body, of which both ends have metal connecting terminals, and metal melt in the tube body. The majority of fuses are cylinder-shaped, namely cartridge construction. But nowadays, with the fast development of advanced technology, some special materials are well applied, the fuse industry has started to move forward in the direction of sub-miniature products and a series of new products such as Surface Mounted Devices type fuse are successively developed.

Applications:

Consumer electronics, mobile devices , home appliances, lighting appliances, power supplies and adapters,  telecommunications equipment, solar electric power and industrial control equipment, etc .Glass fuse is suitable for all kinds of electrical products, It can have a current protection function.

Notice

Have no any rules for the size of mark..

6. appearance

The appearance should not have the stain and crack.

Mark should be easy to be identified.

7. Identify mechanical properties

7.1 tensile strength test

Fixing the fuse, bring to 5N axial tensile force on both ends of the lead, for 1 minute.

After the experiment, the fuse without any damage phenomenon.

7.2 Thrust test

Fixing the fuse,bring to 2N thrust by axial, for 10 seconds.

After the experiment, the fuse without any damage phenomenon.

7.3 Bending strength test(test conditions)

Bending test: Bending 90o with 5N force.

Bending back to count: reciprocating 1 back.

After the experiment, the fuse without any damage phenomenon.

8. Electrical characteristics

8.1 experimental conditions

All test environment temperature is 25 ℃ ±5.

8.2 load ability test

When the fuse through 100% of the rated current, It will not fusing within 4 hours.

8.3 Disjunction ability

The disjunction ability of fuse::10000A use 125V AC Power

                            35A use 250V AC Power(100mA~1A)

100A usd 250V AC Power (1.25A~3.5A)

200A use 250V AC Power(4A~10A)

8.4 The temperature rise test:

With rated current 1.0 times, when the temperature stability (5 minutes when measuring four times,

and each time the measurements and the average does not exceed 2 ℃). Test any part of the fuse body,the temperature rise can’t more than 75 ℃, the ambient temperature of 25 + 5 ℃.8.5
