Unique-Bargains 20A 250V 5x20mm Slow Blow Ceramic Fuse 6pcs

SKU CH-RGGZ-8PFD9

Ceramic time-delay fuses rated 20 A / 250 V in the standard 5 × 20 mm cartridge size, supplied as a pack of six

  • Ceramic tube resists heat during overloads
  • Slow-blow design tolerates brief surge currents
  • 20 A rating protects audio and alarm circuits
  • 250 V rating suits automotive electrical systems
  • Pack of six provides spare fuses for maintenance

Application & Protection

This 20A 250V slow-blow ceramic fuse protects car stereo audio, alarm and amplifier circuits against overload and short circuit. The time-delay design resists surge current without nuisance tripping, making it suitable for equipment that draws high inrush current on start-up.

Who It Suits & Who It Doesn't

Installers and DIYers needing a direct 5x20mm replacement for blown fuses in automotive or low-voltage electronics will find the six-piece pack convenient. Buyers whose equipment requires a fast-acting fuse, a different current or voltage rating, or a non-ceramic body should look at other types.

Deciding Specification

The 5mm diameter by 20mm length form factor is the single dimension that determines whether this fuse fits the holder; verify the original fuse body measurements before ordering.

Questions about this item

What comes in the package and is anything else needed for installation?

The package contains six 20A 250V 5x20mm slow-blow ceramic fuses. No additional parts are required; simply replace the old fuse after disconnecting power.

How do I decide between the listed voltage and current ratings for my equipment?

Match the fuse to your device's specifications: it must be rated for 250 volts and 20 amps. Using a different rating can leave the circuit unprotected or cause nuisance blowing.

What does the 20A 250V slow-blow rating mean when the fuse is fitted in a car stereo or amplifier?

It allows brief current surges above 20 amps — typical when audio equipment powers up — without opening, yet will interrupt a sustained overload to protect the wiring and components.
