cầu chì sứ YORO RS4 AC 1000V Quick-blow 630A 700A 750A 800A 1000A-L104NK

→ Product Overview : RS8 series semiconductor device protection fuses (hereinafter referred to as fast fuses), this series of fast fuses are suitable for AC 50HZ, rated AC voltage 250V-3000V, rated DC voltage 65V-2000V, rated current 10A-16000A In the circuit, it is used as a complete set of rectifier diodes, thyristors and other semiconductor devices for short circuit and certain overload protection that does not allow overcurrent.

         This series of fast-acting fuses is made of a variable cross-section melt made of pure silver sheets and 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 link can be Indicator or striker. When the fuse is melted, the indicator/ striker will act immediately to show that the fuse has been blown (indicator) and push the micro switch ( striker ) to send out various signals or automatically switch circuits. This series of fast-acting fuses have 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.
