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
The rated operating voltage of YCB8-125PV series DC miniature circuit breakers can reach DC1000V, and the rated operating current can reach 125A, which are used for isolation, overload and short circuit protection. It is widely used in photovoltaic, industrial, civil, communication and other systems, and can also be used in DC systems to ensure the reliable operation of DC systems.
Standard: IEC/EN 60947-2.
The rated operating voltage of YCB8-63PV series DC miniature circuit breakers can reach DC1000V, and the rated operating current can reach 63A, which are used for isolation, overload and short circuit protection. It is widely used in photovoltaic, industrial, civil, communication and other systems, and can also be used in DC systems to ensure the reliable operation of DC systems.
