Glossar
Blade fuse
Kurz definiert
A plug-in fuse for circuits in the single- to double-digit amp range — the usual design for load circuits in vehicles and smaller systems.
In der Praxis
It is unsuitable for the main feed: its interrupting capacity is below what a larger battery bank delivers in a short circuit. A high-current fuse belongs there.
The most common weak point is not the fuse but the holder: spring contacts weaken over the years, the fuse sits loosely and creates contact resistance. When troubleshooting, measure across every holder.
