What is a Fusible link?8040312
A fusible link is a short piece of insulated low-voltage cable inside an automotive wiring harness that is designed to shield the harness in applications exactly where a fuse is unsuitable. In an extreme present overload situation, the conductor inside the link is melted while 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 developed to meet specific circuit protection specifications.
What size replacement fusible link should be utilized ?The automotive service business recommends utilizing 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 end of a fusible link and the stripped finish of the cable being protected into a parallel connector as shown, and crimp. A parallel connector should usually be protected with electrical tape or heat-shrink tubing.
What size fusible link should be used in a new installation?The suitability of a fusible link in a new application can be determined only by a qualified harness engineer with complete knowledge of the circuit protection requirements, the installation and operating circumstances, and the security and liability aspects. We cannot make specific recommendations.
