How it works and how to install
The fuse is installed in the equipment's fuse holder, replacing the old blown fuse. When the 3.15A current is exceeded, the internal filament automatically melts, interrupting the electrical circuit and protecting sensitive components. Replacement only requires removing the blown fuse and inserting a new one — a simple process, without special tools. Ensure the equipment is disconnected from the mains before any intervention.
Frequently asked questions
Can I use these fuses with any 220V appliance?
Yes, provided the appliance requires a 3.15A fuse and the fuse holder size is 5x20mm. Check the amperage specified on the casing or in the manual.
How do I know if the fuse is blown?
Look through the transparent glass tube — if the metal filament is broken or the tube shows signs of burning, the fuse needs to be replaced.
How quickly does it react to overload?
It is a fast-blow type, interrupting the circuit within milliseconds of exceeding the nominal current, effectively protecting sensitive electronics.
