Overview:

  This series of fuse is mainly used in solar photovoltaic power generation DC junction box to break off the circuit overload and short circuit current generated by the current feedback of solar panel photovoltaic module and inverter, so as to protect the solar photovoltaic module board, fuse can also be used as line overload and short circuit protection for electrical components in any other DC circuit.

Use of the environment:

 ① The upper limit of ambient air Value shall not exceed + 90℃, and the lower limit of air temperature shall not be lower than-40℃; The altitude of the installation site shall not exceed 3000m;

 ② when the highest humidity is + 40℃, relative moisture of atmosphere is not more than 50%, and it can have higher temperature at lower temperature, for example; When + 25℃, it can reach 90%. As a result of temperature;

 ③ special measures should be taken for condensation occasionally caused by changes;

 ④ in the medium without explosion danger, and the medium has no place which is enough to corrode metal and destroy insulating gas and conductive dust; Pollution level 3.
