What is a Fusible link?8910839
A fusible link is a short piece of insulated low-voltage cable inside an automotive wiring harness that is developed to protect the harness in applications exactly where a fuse is unsuitable. In an extreme current overload scenario, the conductor within the link is melted whilst the ensuing flame and spark is contained inside the link's insulation.
What are the ratings for fusible links?Fusible links are not rated in amps like fuses simply because every installation is unique and developed to meet specific circuit protection specifications.
What size replacement fusible link should be used ?The automotive service business recommends using the same gauge and length as the blown fusible link after the trigger of failure is corrected.
How do you use a parallel connector?Insert the stripped end of a fusible link and the stripped end of the cable being 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 should be utilized in a new installation?The suitability of a fusible link in a new application can be determined only by a certified harness engineer with complete knowledge of the circuit protection requirements, the installation and operating circumstances, and the security and liability aspects. We can't make specific recommendations.
