FAQs
What are the dimensions of these fuses?
These fuses are standard 5mm in diameter and 20mm in length.
Can these be used in home electronics?
While these are designed for automotive use, they are compatible with many electrical devices that require 5x20mm glass fuses and stay within the 250V limit.
How many fuses come in a pack?
Each blister pack contains 10 individual fuses.
Are these fuses fast-acting or slow-blow?
Please check the specific markings on the individual fuse casing within the kit, as performance characteristics depend on the exact amperage rating.
Does the fuse have a polarity?
No, these are standard glass fuses and do not have a specific orientation; they can be installed in either direction.
Why is the glass body beneficial?
The glass body allows for quick, non-destructive visual inspection to see if the internal fuse element has melted, indicating a blown circuit.
Troubleshooting
Fuse blows immediately after installation
There is likely a short circuit in the wiring downstream of the fuse holder. Check the circuit for exposed wires or faulty components.
Fuse fits loosely in the holder
Ensure the holder is designed for 5mm x 20mm fuses. If the holder clip is loose, it may need to be carefully tightened to ensure a secure connection.
Visible oxidation on the fuse holder contacts
Clean the metal tabs of the fuse holder with contact cleaner or a small wire brush before installing the new fuse to ensure optimal conductivity.
Pros and Cons
Pros
- Reliable OE-quality protection
- Corrosion-resistant nickel-coated contacts
- Durable glass construction for easy inspection
- Standardized 5x20mm sizing for broad compatibility
- Convenient 10-piece pack size
Cons
- Limited to specific 5x20mm fuse holders
- Requires manual verification of amperage ratings
- Glass fuses are more fragile than ceramic or blade types
Setup, Compatibility & Care
To install, ensure the vehicle ignition is turned to the 'Off' position and all electrical loads are deactivated. Locate your vehicle's fuse box, identify the faulty fuse using the diagram provided in your owner's manual, and use a proper fuse puller tool to remove the old unit. Before inserting a Hella replacement fuse, verify that the amperage rating matches the circuit requirement exactly. Do not use a fuse with a higher amperage rating than specified, as this can lead to wiring damage or fire. These fuses are maintenance-free, but it is recommended to keep them in a dry, cool environment within the original packaging to prevent physical damage to the glass.
