What is a Fusible link?4305731
A fusible link is a short piece of insulated low-voltage cable inside an automotive wiring harness that is developed to protect the harness in applications where a fuse is unsuitable. In an intense present overload scenario, 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 distinctive and designed to meet specific circuit protection requirements.
What size replacement fusible link should be used ?The automotive service business recommends using the exact 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 finish 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 ought to 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 understanding of the circuit protection specifications, the installation and operating conditions, and the safety and liability elements. We can't make particular recommendations.
