YCF8-32PV Photovoltaic DC Fuse

General
The YCF8-32 PV series fuse is designed with a rated operating voltage of DC1500V and a current rating of 80A, making it suitable for use in solar photovoltaic DC combiner boxes. Its primary function is to interrupt line overload and short-circuit currents that may arise due to current feedback from solar panel components and inverters, providing essential protection to the photovoltaic components. This fuse is integral to preventing damage in solar power systems by isolating and protecting individual circuits, thereby enhancing the reliability and safety of the entire photovoltaic setup.
Standard: IEC60269, UL4248-19.

General

The variable cross-section melt made of pure silver sheet (or silver wire winding) is soldered with low-temperature tin and packaged in a fusion tube made of high- strength porcelain. The fusion tube is filled with chemically treated and specially processed Process-treated high-purity quartz sand is used as the arc-extinguishing medium, and the two ends of the melt are firmly electrically connected with the contacts by electric welding.
