In an extreme current overload scenario, 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 distinctive and designed 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 after the cause of failure is corrected. How do you use a parallel connector?Insert the stripped end 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 should be utilized 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 conditions, and the security and liability elements.
