Fast fuse for semiconductor device protection

   → Product introduction

  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.
