What it is
The Bussmann S500-80-R is a pack of five fast-acting glass fuses rated at 80 mA and 250 V AC. They are designed for line protection in low-current circuits where a quick response to overcurrent is required. Each fuse has an interrupt rating of 35 A at 250 V AC. The cylindrical body measures 20 mm in length and 5 mm in diameter. They suit technicians and hobbyists maintaining equipment that uses this specific fuse size and rating.
Build and fit
The glass body lets you inspect the element visually after a fault. The non-rejection style means they fit standard 5 mm x 20 mm fuse holders without a keyed slot. They are compatible with HTB series fuse blocks and match the Bussmann GDB, S500, Littelfuse 217 and Mersen GSB series. The single-element construction provides straightforward overcurrent protection. CE, CSA and UL Guide JDYX2 markings confirm compliance with recognised safety standards.
Deciding spec
The critical figure is the 80 mA current rating; the fuse will open quickly if current exceeds this value. Verify that your circuit demands exactly this rating and a 250 V AC voltage rating before fitting. Using a higher or lower amperage fuse will not protect the circuit correctly. The 35 A interrupt rating shows the maximum fault current the fuse can safely break at 250 V AC.

Questions about this item
What does the 35A interrupt rating at 250V AC mean for this fuse?
It means the fuse can safely interrupt a fault current up to 35 amps at 250V AC without rupturing.
What are the physical dimensions needed for this fuse to fit?
The fuse measures 20mm long by 5mm in diameter, matching the standard 20mm x 5mm cylindrical size.
How do I install these glass fuses and what mistake should I avoid?
Insert each fuse into a compatible HTB series fuse block; do not solder directly to the glass body as heat can damage it.
