Ceramic Cartridge Fuses 6.3A 250V
This pack contains six 5x20mm slow-blow ceramic fuses rated at 6.3 amps and 250 volts. They protect automotive and audio circuits such as car stereos, alarms and amplifiers from overload and short-circuit damage. The time-delay characteristic withstands brief surge currents without nuisance tripping.
Simple Glass-Tube Replacement
Installation requires only pulling the old fuse from its holder and pressing the new one in after power is disconnected. The main risk is fitting a fuse with the wrong current or voltage rating, which defeats protection or causes premature blowing. Verify the original 5mm diameter and 20mm length before fitting.
Suits 6.3A 250V 5x20mm Holders
These suit owners replacing identical slow-blow fuses in compatible holders. They do not suit circuits needing fast-acting fuses, higher current ratings, different physical dimensions or lower voltage ratings. Buyers who need a different ampere value or fuse speed should look elsewhere.
Highlights
- Slow-blow design tolerates startup surges

Questions about this item
How do I verify the 6.3A 250V ceramic fuse is working correctly after installation?
Restore power and confirm the protected circuit operates normally without the fuse opening; a slow-blow 6.3A 250V fuse should tolerate brief surge currents while still interrupting sustained overloads.
What comes in the pack and is anything else required for replacement?
The package contains six 5x20mm ceramic-tube fuses with nickel-plated brass end caps; no additional parts are needed if the holder matches the 5mm diameter and 20mm length.
Which fuse rating should I choose for a car stereo amplifier that specifies a 6.3A 250V slow-blow type?
Select the 6.3A 250V slow-blow ceramic fuse — matching the exact rated current, voltage, 5x20mm size and time-delay characteristic ensures proper protection.
