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.

Features

The fuse base is made of a plastic pressed shell with contacts and fuse-carrying parts, which are riveted and connected, and can be used as the supporting part of the fuse link of corresponding size. This series of fuses has the characteristics of small size, convenient installation, safe use and beautiful appearance.

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.
