NOTE
Only select fuses suitable for a voltage of 600 V DC.
Example:
Maximum short circuit current (I
SC
) of the solar module = 5.75 A
According to the criteria for selecting the correct fuse, the fuse must have
a nominal current greater than 1.5 times the short circuit current:
5.75 A x 1.56 = 8.97 A
The fuse that should be selected according to the ‘Fuses’ table: KLK D 9
