A fuse (fuse) is also called a current fuse or a fuse, and the IEC127 standard defines it as a "fuse-link". It is an electrical component installed in a circuit to ensure the safe operation of the circuit. A wire made of a silver-copper alloy with a relatively high resistivity and a low melting point is called a fuse. Fuses originally made of lead-antimony alloys have been phased out for safety reasons.

Classification of fuses:

Fuses are classified by type and can be divided into:

1. Current fuses (chip fuses, miniature fuses, insert fuses, tubular fuses, automotive fuses);

2. Thermal fuse (RH [block type], RP [resistance type], RY [metal shell]);

3. Self-recovery fuse (plug-in, lamination, patch).

Fuse_Fuse UL certification standard:

UL 248-1 general requirements apply to low-voltage fuse-links rated at 1000 V or less, AC and/or DC, with interrupting ratings up to 300 kA (200 kA in Mexico).

UL 248-14 Supplementary fuses apply to fuses rated 60 A or less for supplemental overcurrent protection only and not for branch circuit or equivalent applications. DC rating is optional.

UL 248-13 Semiconductor fuses apply to semiconductor fuses rated at 2000 V ac or less. DC rating is optional.

Fuse_Fuse UL certification test items:

Voltage drop test, temperature rise test, fusing characteristic test (overload test), breaking test, insulation resistance test

application process:

1. Send samples

2. Fill in the application form (applicant company name address product name address manufacturer company name address information corresponding to the platform)

3. Make a quotation and sign and seal the contract (pay first and then open the case to test the product)

4. Test 7 working days according to the time when the sample is sent

5. Issue a draft report to confirm that the information is correct

6. Issue a formal report
