      Installation & Engineering Guidelines<\/h2>\n
        \n
      • Maximum rated working voltage is 32V DC. Do not apply to circuits exceeding this rating.<\/li>\n
      • Use together with matched ATM \/ APM mini blade fuse holder to ensure stable contact performance.<\/li>\n
      • Replace fuse only after fault elimination; never use higher-rated fuse for bypass protection.<\/li>\n
      • Designed to withstand temperature variation inside vehicle cabins and engine compartments.<\/li>\n
      • For mass production projects, confirm full datasheet and test report before formal order release.<\/li>\n<\/ul>\n
