→Product Overview : RSG series of fuse for semiconductor device protection (hereinafter referred to as fast fuse), this series of fast fuse is suitable for AC 50HZ, rated AC voltage 250V-3000V, rated DC voltage 65V-2000V, rated current 10A-16000A In the circuit, as a set of rectifier diodes, thyristors and other semiconductor devices, short circuit and certain overload protection that do not allow overcurrent.

         This series of fast fuses are made of pure silver sheets. The variable cross-section melt is encapsulated in a fuse tube made of high-strength porcelain; the fuse tube is filled with chemically treated high-purity quartz sand as the arc extinguishing medium; the fuse can be brought Indicator or striker, when the fuse is blown, the indicator/ striker will act immediately, showing that the fuse has been blown (indicator) and pushing the micro switch (strike) to send out various signals or automatically switch the circuit. This series of fast fuse has the characteristics of large rated capacity, high breaking capacity, fast fusing speed, obvious current limiting characteristics, obvious indication, safety and reliability. This series of fuse-links complies with the national standard GB/T13539.4 and the International Electrotechnical Commission standard IEC60269-4.

→Normal working conditions
     1. The altitude of the installation site does not exceed 2000M;
     2. The upper limit of ambient air temperature does not exceed +40℃, and the lower limit does not fall below -5℃. Under such conditions, condensation due to temperature changes is not allowed of;
     3. Install in a non-explosive medium, where there is no gas
     that can corrode metal and damage insulation, and no conductive dust; 4. The product can be installed vertically, horizontally or obliquely, and there is no significant vibration and impact in the workplace;
     5. The product When the rated current of the product is greater than 1250A, and it is used for a long time above 70% of the rated current, it must be connected to a water-cooled bus or forced air-cooled;
