General
The variable cross-section melt made of pure silver sheet (or silver wire winding)is soldered with low-temperature tin and packaged in afusion tube made of high- strength porcelain.The fusion tube is flled with chemically treated and specially processed Process-treated high-purity quartz sand isused as the arc-extinguishing medium,and the two ends of the melt are firmly electrically connected with the contacts byelectric welding
General
YCS8-S series Photovoltaic DC Surge Protective Device is applicable to photovoltaic power generation system. When surge overvoltage occurs in the system due to lightning stroke or other reasons, the protector immediately conducts in nanosecond time to introduce the surge overvoltage to the earth, thus protecting the electrical equipment on the grid.

General
YCF8-PV series fuses have a rated operating voltage of DC1500V and a rated current of 80A. It is mainly used in the solar photovoltaic DC combiner box to break the line overload and short-circuit current generated by the current feedback of the photovoltaic components of the solar panel and the inverter, so as to protect the solar photovoltaic components. It is widely used in the circuit protection of electric drive system, power supply system and auxiliary system, and the fuse can also be selected in any other DC circuit as the circuit overload and short circuit protection of electrical components.
Standard: IEC60269, UL4248-19.
