H22F07 25A-100A fast fuse 690V700V

H22F07 Semiconductor Fast Fuse

1． Use and use

This series of fuses is suitable for circuits with rated AC voltage IEC (690V) UL (700V) DC 600V and rated current 25A-100A. The 80KA (AC) and 50KA (DC) segmented capabilities are mainly used for line overload and short circuit protection in electrical equipment, UPS system protection for small inverters, variable speed drive protection, and other similar 700V protection. The product complies with the provisions of the national standard GB13539-4, the International Power Commission standard IEC60269-4, and UL248-1/248-13

2．operational condition

The upper limit of ambient air temperature shall not exceed 125℃; the lower limit of ambient air temperature shall not be lower than-40℃; the altitude of the installation site shall not exceed 2000m (if exceeding this 2000m, the requirements shall be indicated, and the Company can design and develop according to customer requirements).

3.  Usage category

"aR" indicates the fuse used to protect the line overload and short circuit in the electrical device.

4．Structural characteristics

The variable cross-section melt made of 99.99% pure silver is encapsulated in a melt tube made of high-strength ceramics. The melt tube is filled with chemically treated high-purity quartz sand and specially treated chemicals as arc extinguishing media, and both ends of the melt are firmly electrically connected to the contacts.

5. Main technical parameters

Can be customized according to customer requirements. The test data was conducted at a constant temperature of 23.5 degrees Celsius
