BS ISO 8820-6-2019 pdf free download.Road vehicles – Fuse-links Part 6: Single-bolt fuse-links.
This document specifies single-bolt fuse-links in road vehicles. It establishes, for this fuse-link type, the rated current, test procedures, performance requirements and dimensions.
This document is applicable to those fuse-links with a rated voltage of 58 V, a current rating of s300 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 48 V.
