14x51 PV fuse size and fuse holder for 1500VDC Solar System Application: BZCF series of fuses for rated DC voltage to 1500V, the coiurated current to 30A of the line, and the photovoltaic panels and batteries in series in parallel, the charge converter system to do short-circuit break protection; the same time, Variable rectifier system and short circuit fault breaking protection; and do photovoltaic power generation system inrush current and short circuit fault over-voltage fast breaking protection, rated breaking capacity of 20KA, and Division I is now doing the relevant test, once again enhance the product breaking capacity, Comply with the relevant standards IEC60269, GB13539, UL42428 requirements. Normal working conditions: The ambient air temperature limit of not more than 90 ºC; the ambient air temperature lower limit of not less than -50 ºC; installation site altitude of not more than 2000m (if more than 2000m, need to specify the requirements, the company can be designed and developed in accordance with customer requirements). Use category "gPV" indicates a DC fuse for full range breaking capability for over-current protection of solar PV systems. 4. Structural features This product is made of 99.99% pure silver piece made of variable cross-section melt encapsulated in 95% AL2O3 high strength porcelain made of molten pipe, the melting tube filled with chemically treated high purity quartz sand and special treatment of chemical materials as off Arc medium, the contact surface with silver processing, the two ends of the melt using spot welding and contact firmly connected.
