Intelligent fuses are innovative automotive style fuses that feature an LED indicator light that glows when the fuse is blown, saving time to troubleshoot an open circuit. The major benefit to an intelligent fuse is that it is easy to find a blown fuse in a fuse block mounted behind a dimly lit dashboard or under the hood of your car. This gives the user the ability to quickly return his or her vehicle to operation. Intelligent fuses are designed to fit all fuse block configurations offered by American Autowire and are drop-in replacements for existing OEM and after market automotive ATO/ATC and mini fuse applications.
The second picture shows two light circuits individually protected by a intelligent fuse. When the circuit is functioning normally, the fuse has a normal appearance. Where there is a problem in the circuit that has caused the fuse is blow, the light circuit is dead and the intelligent fuse lights up indicating a blown fuse.
The intelligent fuses carried by American Autowire meet stringent SAE specifications for operation and material components. Note that the fuses still maintain the circuit test capability for the load and output side of the fuse. This is important when testing an operational circuit. Many other fuses do not retain this function.
