IEC 60269-7 Ed. 1.0 b:2021

These supplementary requirements apply to fuse-links for the protection of batteries and battery systems, including, but not limited to terminology, for electricity storage in equipment for circuits of nominal voltages up to 1 500 V DC.

Their rated voltage can be higher than 1 500 V DC.

The object of these supplementary requirements is to establish the characteristics of battery fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics, provided that their dimensions are identical.
