It establishes, for this fuse-link type, the rated current, test procedures, perfo
12、rmance requirements and dimensions. This part of ISO 8820 is applicable to fuse-links with a rated voltage of 58 V, a current rating of u 300 A and a breaking capacity of 2 000 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
13、 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. 2 Normative references The following referenced documents are indisp
