  • What is the difference between UL and IEC fuses?

    ​UL (Underwriters Laboratories) and IEC (International Electrotechnical Commission) are two different standards organizations that establish safety standards and certification requirements for various electrical products, including fuses. The main difference between UL and IEC fuses lies in the standards they adhere to and the regions where they are commonly used:

  • Working principle of high speed fuse

    high speed fuse is designed for circuits that need to be quickly disconnected from the current. Its working principle is that when the circuit is overloaded or short-circuited, the internal thermal fuse of the high speed fuse will rapidly increase in temperature. high speed fuse is designed for circuits that need to be quickly disconnected from the current.
