H14FD/H14FF Semiconductor Fast Fuse
1． Use and use
This series of fuses is suitable for circuits with rated AC voltage IEC (690V) UL (700V) and DC (600V) rated current 1A-63A. The 100KA (AC) and 50KA (DC) segmented functions 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 national standard GB13539-4, 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).
- Usage category
“aR” indicates the fuse used to protect the line overload and short circuit in the electrical device.
