What is a Fusible link?558142
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 present overload scenario, the conductor inside the link is melted whilst the ensuing flame and spark is contained inside the link's insulation.
What are the ratings for fusible links?Fusible links are not rated in amps like fuses simply because every installation is unique and designed to meet specific circuit protection specifications.
What size replacement fusible link should be used ?The automotive service industry recommends utilizing the 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 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 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 full knowledge of the circuit protection requirements, the installation and operating conditions, and the security and liability elements. We can't make specific recommendations.
