BS ISO 8820-10:2020 pdf download – Road vehicles — Fuse-links Part 10: Fuse-links with tabs Type L (high current miniature)
This document specifies fuse-links with tabs (blade-type) Type L (high current miniature) for use in road vehicles. It establishes, for this fuse-link type, the rated current, test procedures, performance requirements and dimensions. This document is applicable for fuse-links with a rated voltage of 32 V, a current rating of ≤60 A and a breaking capacity of 1 000 A intended for use in road vehicles. This document is intended to be used in conjunction with ISO 8820-1 and 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 document.
