What is a Fusible link?6421101
A fusible link is a brief piece of insulated low-voltage cable within an automotive wiring harness that is designed to shield the harness in applications 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 distinctive and developed to meet particular circuit protection specifications.
What size replacement fusible link should be utilized ?The automotive service industry recommends utilizing the same gauge and length as the blown fusible link following 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 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 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 complete understanding of the circuit protection requirements, the installation and operating circumstances, and the security and liability aspects. We cannot make specific suggestions.
