    Short Description:

    The variable cross-section fuse element made of pure silver sheets are sealed in the melting tube made of epoxy glass fibre which is heat resistant. The fuse tube is filled with chemically-treated high-purity quarts as arc-extinguishing medium,The two ends of the melting body are connected to the (knife) contacts by dot welding.

    Applications

    This series of fuses are mainly used in circuits of AC 50Hz, rated voltage of 2000V and rated current of 2500A, to protect the semiconductor components and the whole unit from circuit short (aR). The breaking capacity of the fuses is up to 100kA.

    The fuses are compliant with the IEC60269-1 / IEC60269-4 and GB13539.1 / GB/T13539.4.

    Design Features

    The variable cross-section fuse element made from pure silver sheets are sealed in the melting tube made of high-density porcelain; The fuse tube is filled with chemically treated high purity quarts as arc-extinguishing medium; The two ends of the melting body are connected to the (Knife) contactor by dot welding; Both knife contactors and board contacts are available;

    A striker / indicator may be installed to the fuse link, When the fuse link breaks, signals are sent out in the case of an indicator, or the switch is pushed to cut the circuit the case of a striker.
