What is a Fusible link?4448910
A fusible link is a short piece of insulated low-voltage cable inside an automotive wiring harness that is developed to shield the harness in applications exactly where a fuse is unsuitable. In an extreme current overload situation, the conductor within 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 simply because each installation is unique and developed to meet specific circuit protection requirements.
What size replacement fusible link should be utilized ?The automotive service industry recommends using the exact 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 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 certified harness engineer with full understanding of the circuit protection requirements, the installation and operating conditions, and the security and liability elements. We can't make specific suggestions.
