Scope: The supplementary requirements of this part apply to the fuse links of photovoltaic module strings and photovoltaic arrays in protective equipment, and the fuse links are suitable for circuits with a nominal voltage up to 1 500 V DC. The rated voltage of the fuse link can reach 1500 V DC. The purpose of this standard is to determine the characteristics of PV fuse-links, so that under the premise of the same size, photovoltaic fuse-links can be replaced by other types of fuse-links with the same characteristics. Therefore, this section specifies in particular: a) the following characteristics of fuse-links: 1) rated value; 2) use category; 3) temperature rise during normal operation; 4) power dissipation; 5) time-current characteristics; 6 ) Breaking capacity; 7) Dimensions or dimensions (if applicable); b) Type test to verify the characteristics of the fuse link; c) Marking of the fuse link.
