    2. Working voltage
    3. Ambient temperature
    4. Overload current and cutout time
    5. Possible malfunction current
    6. Impulse current, surge current, starting current and transient value of the line
    7. Size and dimensions, connection methods, indicators, etc.

    Ambient Temperature:
    Ambient Temperature means the air Temperature directly around the fuse, and should not be understood as the room temperature. In many application cases, the fuses are at rather high temperature as they are installed with supporting devices or bases in different structures and they are closed in the distributing or controlling boxes.
