SKU CH-FDRJ-TP10M

Pack of five 20 mm glass fuses rated 400 mA at 250 V AC with a 35 A interrupt rating

  • Time-delay action protects circuits from inrush currents
  • 35 A interrupt rating at 250 V AC handles fault currents safely
  • 20 mm × 5 mm cylindrical glass body fits standard fuse holders
  • cURus, IMQ and MITI/JET certifications confirm compliance with recognised standards
  • Pack of five fuses provides ready spares for maintenance

Bussmann S506-400-R Glass Fuse 5-Pack

This pack contains five Bussmann S506-400-R glass fuses rated at 400 mA and 250 V AC. Each fuse features a time-delay characteristic and a cylindrical body measuring 20 mm in length and 5 mm in diameter. They are designed for circuit protection in compatible equipment. The pack suits technicians and hobbyists needing multiple replacements.

Replaces GDC 218 GDG S506 Series Fuses

These fuses serve as direct equivalents for Bussmann GDC, Bussmann S506, Littelfuse 218, and Mersen GDG series parts. The jump is worth it when your existing fuse carries the same 400 mA 250 V AC rating and 35 A interrupt rating. They fit holders designed for the standard 20 mm by 5 mm cylindrical form factor.

Verify Holder Series and Electrical Rating

Before ordering, confirm your fuse block accepts the HTB series or an equivalent 20 mm by 5 mm cylindrical fuse. Check that the circuit requires a 400 mA time-delay fuse with a 250 V AC voltage rating and a 35 A interrupt capacity. Ensure the application does not need a rejection-style fuse body.

Questions about this item

Will the 20 mm by 5 mm cylindrical body fit my existing fuse holder?

The fuse body measures 20 mm long and 5 mm in diameter, matching standard 5 × 20 mm holders such as the HTB series.

How do I install these time-delay glass fuses without damaging them?

Insert each fuse straight into the clips with gentle pressure; the common mistake is twisting the glass body, which can crack the element.

When should I replace a fuse from this 5-pack after it blows?

Replace it immediately with another 400 mA, 250 V AC, time-delay fuse carrying the same 35 A interrupt rating.
