WESTKING 10X38mm PV fuse holder has exceeded 30 million units in photovoltaic power generation applications in China. Since photovoltaic fuses are typically used outdoors in harsh environments with significant temperature differences, there are strict requirements for the material selection of photovoltaic fuses. During the research and development stage, WESTKING New Energy Technology Co., Ltd. conducted extensive simulated working condition tests and validations. By referring to actual operating conditions in the market and considering environmental factors, WESTKING finally created a photovoltaic holder that can withstand harsh environmental testing conditions. This has resulted in excellent word of mouth in the Chinese market, with high evaluations from users for our products in many technical transformation project bidding samples.
Below is a table of environmental derating coefficients for 10X38mm PV fuse holder application environments, along with installation and wiring instructions. Please read it carefully, as it is crucial for the correct use of photovoltaic fuses and can reduce faults while extending the service life of the fuse holder.
Maximum tightening torque: 2Nm
For rigid or multistrand wire with a size of 1-16mm² (16-6AWG), WESTKING recommend using a maximum of 2x6mm² PZ2 or 5.5x1mm flat screw drivers (with a maximum diameter of 6mm).
