    products description

    Normal working conditions
    The upper limit of ambient air temperature shall not exceed 75 ℃; The lower limit of ambient air temperature shall not be lower than -40 ℃; The altitude of the installation location shall not exceed
    Beyond 3500m (if you want to exceed this value, please specify the requirements, and our company can design and develop according to customer requirements), relatively
    The air humidity should not exceed 90%.
    Usage category
    AR "represents the use of fast DC fuses for new energy protection.
    Structural characteristics
    The variable cross-section melt made of silver is encapsulated in a high-strength melt tube, which is filled with chemically treated high-purity quartz
    Sand and special treatment chemicals are used as arc extinguishing media, and the two ends of the melt are firmly connected to the contacts through spot welding.
    Short circuit melting characteristics
    The fuse melts within 6 seconds when subjected to 4 times the overload current, and within 0.02 seconds when subjected to 8 times the overload current
    The fuse is prone to short circuit protection as it melts within 0.005 seconds when subjected to 20 times the overload current.
