Bussmann S506-315-R Glass Fuse 5 Pack
The Bussmann S506-315-R is a cylindrical glass fuse rated at 315mA and 250V AC with a 35A interrupt rating. It suits technicians and hobbyists needing time-delay protection for low-current circuits in equipment such as power supplies or control panels. The pack contains five identical fuses for spares or multi-point replacement.
Installation and common issues
Each fuse measures 20mm long by 5mm diameter and fits standard 5x20mm fuse holders or compatible HTB series blocks. Installation requires no tools beyond opening the holder and seating the fuse. The glass body allows visual inspection of the element. Common issues include using a fast-acting fuse where time-delay is required, causing nuisance blows, or exceeding the 250V AC rating.
Pre-order checks
Verify that your equipment specifies a 315mA time-delay fuse at 250V AC and accepts a 5x20mm cylindrical body. Confirm the holder is non-rejection type and rated for at least the available fault current. Cross-reference the S506 series with equivalents such as GDC, 218 or GDG if the service manual lists those designations. Ensure the application does not demand a higher interrupt rating than 35A.

Questions about this item
How do I confirm the fuse is working correctly after installation?
The circuit should remain powered under normal load; if the fuse opens, the glass body will show a visible break in the internal element, indicating it has interrupted a fault current up to 35A at 250V AC.
What comes in the pack and is any accessory required for mounting?
The pack contains five 20mm x 5mm cylindrical glass fuses rated 315mA, 250V AC, time-delay, non-rejection type; they fit compatible HTB series fuse blocks, which are sold separately.
Which version should I choose if I need a direct replacement for a Bussmann GDC or Littelfuse 218 fuse?
This S506-315-R is the direct equivalent to Bussmann GDC, Bussmann S506, Littelfuse 218 and Mersen GDG series fuses with the same 315mA, 250V AC, 35A interrupt rating.
