What is a Fusible link?5504929
A fusible link is a short piece of insulated low-voltage cable inside an automotive wiring harness that is designed to protect the harness in applications exactly where a fuse is unsuitable. In an intense 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 because every installation is unique and designed 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 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 end 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 specifications, the installation and operating circumstances, and the safety and liability elements. We can't make particular suggestions.
