Описание (английский):

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 ≤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 48 V.

Overview

ISO 8820-6:2019 - "Road vehicles - Fuse-links - Part 6: Single-bolt fuse-links" defines the design, test procedures, performance requirements and dimensions for single-bolt fuse-links used in road vehicles. This second edition (2019) replaces the 2007 edition and applies to fuse-links with a rated voltage of 58 V, current ratings ≤ 300 A, and a breaking capacity of 2 000 A, intended for use in nominal vehicle voltages of 12 V, 24 V and/or 48 V.

Key topics and technical requirements

Scope & compatibility

Intended to be used in conjunction with ISO 8820-1 (definitions and general test requirements) and ISO 8820-2 where relevant.

Rated values

Rated voltage: 58 V; current ratings listed (30, 40, 50, 75, 100, 125, 150, 175, 200, 225, 250, 300 A).
Breaking capacity: 2 000 A.

Mechanical & electrical design

Definition of an insulating nut and requirements for terminal finishes and corrosion protection.
Mounting torque specified at (12 ± 1) Nm.
Insulating nut insulation resistance ≥ 200 kΩ (measured at 100 V DC).

Test procedures & performance

Test sequence and grouping across mechanical, electrical and environmental tests (minimum sample groups of 10).
Voltage drop limits specified per fuse rating (e.g., 30 A → max 120 mV; 300 A → max 70 mV).
Operating time ratings with defined limits at multiple multiples of In (1.0 I, 1.35 I, 1.5 I, 2.0 I, 3.5 I, 6.0 I).
Transient current cycling performed at (90 ± 5) °C with defined on-time/current profiles.
Breaking capacity test at 2 000 A using specified test cable sizes (per ISO 6722-1 conductor guidance).
Strength tests for insulating body and insulating nut - components must remain physically intact after mechanical stress.

Test fixtures & dimensions

Detailed test-fixture specifications, cable-size tables and dimension drawings are provided to ensure repeatable test conditions.

Applications

Ensures reliable short-circuit and overload protection for electrical distribution in passenger cars, light and heavy commercial vehicles, and electrical subsystems operating at 12 V, 24 V or 48 V.

Used for component specification, vendor qualification, type testing, and compliance verification in vehicle electrical system design and manufacturing.
