Five cylindrical glass fuses with metal end caps

Bussmann

Bussmann S506-800-R Glass Fuse 800mA 250V AC 35A 5 Pack

SKU CH-QY3T-RV024

Five-pack of 20 mm glass time-delay fuses rated 800 mA at 250 V AC with a 35 A interrupt rating

  • Time-delay protection handles surges without nuisance blows
  • 800 mA rating at 250 V AC suits low-current circuits
  • 35 A interrupt rating clears faults safely
  • 20 mm × 5 mm glass body fits standard holders
  • Pack of five provides ready spares

Glass Fuse Pack for Low-Current Protection

The Bussmann S506-800-R is a glass-bodied fuse rated at 800 mA and 250 V AC. It suits equipment that requires a time-delay response for transient surges. The cylindrical 20 mm by 5 mm body fits standard holders used in control panels and instrumentation. Supplied as a five-piece pack for spares or multiple circuits.

Cylindrical Body Fits HTB Fuse Blocks

Glass construction allows visual confirmation of element status after a fault. The non-rejection style seats in compatible HTB series fuse blocks without a keyed notch. A 35 A interrupt rating at 250 V AC handles short-circuit energy in protected low-power branches. Single-element design simplifies replacement without special tools.

Direct Cross for GDC 218 and GDG Series

This S506 series fuse replaces Bussmann GDC, Littelfuse 218 and Mersen GDG parts where identical ratings apply. The jump is worth it when existing fuses carry cURus, IMQ or MITI/JET markings and a time-delay characteristic is specified. Buyers needing a faster-acting or higher-current element should select a different series.

Questions about this item

What interrupt rating does the 250 V AC glass fuse provide?

The fuse interrupts up to 35 A at 250 V AC, limiting fault current in the protected circuit.

What are the length and diameter dimensions for the cylindrical body?

The fuse measures 20 mm long by 5 mm in diameter, matching the standard 20 mm × 5 mm cartridge size.

How are these time-delay fuses installed in a compatible holder?

Insert each fuse into a suitable HTB series fuse block until the glass body seats fully; the common mistake is forcing a mismatched diameter fuse into the clips.
