What is a Fusible link?1508629
A fusible link is a short piece of insulated low-voltage cable within an automotive wiring harness that is designed to protect the harness in applications where a fuse is unsuitable. In an intense current overload scenario, the conductor inside the link is melted whilst the ensuing flame and spark is contained within the link's insulation.
What are the ratings for fusible links?Fusible links are not rated in amps like fuses because every installation is unique and designed to meet particular circuit protection specifications.
What size replacement fusible link ought to be used ?The automotive service industry recommends using the same gauge and length as the blown fusible link following the cause of failure is corrected.
How do you use a parallel connector?Insert the stripped finish of a fusible link and the stripped end of the cable becoming protected into a parallel connector as shown, and crimp. A parallel connector should always be protected with electrical tape or heat-shrink tubing.
What size fusible link ought to be used in a new installation?The suitability of a fusible link in a new application can be determined only by a certified harness engineer with full knowledge of the circuit protection requirements, the installation and operating conditions, and the security and liability aspects. We cannot make specific recommendations.
