FUSING
The correction factor of a fuse shall be determined by an authorized professional electrical engineer
in accordance with the relevant design regulations and system simulation results. Trina Solar does
not responsible for determining the minimum rating of fuse.
The fuse rated current should be chosen depending on different standards, as follows

A correction factor (

) should be applied for determining the fuse rated current working at different
temperatures. Please confirm the final fuse selection with the qualified design institutes and fuse
manufacturer. The
maximum series fuse rating value on the products’ datasheet provided by Trina
Solar should be used for reference only.
