The 20-Amp Intelligent MAXI Blade Fuse combines standard circuit protection with a convenient visual blown-fuse indicator, making electrical troubleshooting faster and easier.

When a conventional fuse blows, finding the failed fuse can require removing individual fuses or checking them with a test light or multimeter. This intelligent fuse simplifies the process with a built-in indicator designed to glow when the fuse has blown, providing an immediate visual reference to the affected circuit.

Rated at 20 amps, this fuse is designed for compatible circuits requiring a 20A MAXI-style blade fuse. The larger MAXI blade format is commonly used for higher-current automotive and vehicle electrical applications.

The glow indicator can be particularly useful in fuse panels containing multiple circuits, where quickly locating the affected fuse can save valuable diagnostic time. Instead of inspecting every fuse individually, technicians, vehicle owners, installers, and fleet maintenance teams can more easily identify the circuit requiring attention.

Its practical design makes it a useful replacement or upgrade for compatible cars, trucks, RVs, motorhomes, trailers, commercial vehicles, specialty vehicles, and other electrical systems using MAXI blade fuses.

For RV and commercial applications, where vehicles may contain numerous electrical accessories and circuits, easier fuse identification can simplify both roadside troubleshooting and routine maintenance.

This package contains one 20-amp intelligent MAXI blade fuse, making it ideal as an individual replacement or spare.

Always replace a blown fuse with the same fuse type and amperage rating specified by the vehicle or equipment manufacturer. A blown fuse may indicate an underlying electrical problem that should be diagnosed before replacing the fuse.
