Bussmann S506-8-R Glass Fuse 8A 250V 80A 5 pack line protection
Pack of five 20 mm glass time-delay fuses rated 8 A at 250 V AC with an 80 A interrupt rating
- Time-delay characteristic handles temporary surges without nuisance trips
- 8 A rating protects circuits up to 80 A interrupt at 250 V AC
- Glass cylindrical body fits standard 20 mm × 5 mm fuse holders
- cURus, IMQ and MITI/JET recognition confirms safety compliance
- Pack of five provides ready spares for maintenance or replacement
Purpose & Audience
These glass tube fuses provide 8 A, 250 V AC time-delay protection for circuits that experience brief inrush currents. They suit technicians, hobbyists and maintenance teams who need reliable line protection in panels, appliances or low-voltage equipment. Buyers who require a higher interrupt rating or a different form factor will need an alternative solution.
Build & Connections
The cylindrical glass body measures 20 mm long by 5 mm in diameter and fits standard 5 × 20 mm fuse holders or compatible HTB series blocks. A single-element, non-rejection design allows simple insertion and removal without special tools. The 80 A interrupt rating at 250 V AC meets cURus, IMQ and MITI/JET recognition for compliant installations.
Accessories & Extras
Each pack contains five fuses, giving spares for multi-circuit boards or future replacements. No additional hardware, software or documentation is bundled, so installers should verify holder compatibility and local code requirements before use.

Questions about this item
What does the 80 A interrupt rating at 250 V AC mean for this fuse?
It means the fuse can safely break a fault current up to 80 amps at 250 volts AC without rupturing, making it suitable for line protection where short-circuit currents stay below that level.
What physical dimensions must the fuse holder accommodate for these 5 mm × 20 mm cylindrical fuses?
The holder needs to accept a 5 mm diameter by 20 mm long glass body; compatible block series include HTB and the fuse is non-rejection style so no special keying is required.
How are these time-delay glass fuses installed, and what common mistake should be avoided?
Push each fuse straight into the clips of a suitable HTB-type block until fully seated; the mistake is twisting or forcing the glass body, which can crack the tube and ruin the element.
