This Part of ISO 8820 is applicable to those fuse-links with a rated voltage of 58 V, a current rating of <= 300 A and a breaking capacity of 2000 A intended for use in road vehicles at a nominal voltage of 12 V, 24 V and/or 42 V.
This Part of ISO 8820 is intended to be used in conjunction with ISO 8820-1 and with ISO 8820-2. The numbering of its clauses corresponds to that of ISO 8820-1, whose requirements are applicable, except where modified by requirements particular to this part of ISO 8820.
