What is a Fusible link?2441792
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 situation, 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 each installation is unique and developed to meet specific 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 after 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 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 qualified harness engineer with full understanding of the circuit protection specifications, the installation and operating circumstances, and the security and liability elements. We cannot make particular suggestions.
