SKU CH-6KXN-PRK5H

Fast-acting 5 A glass fuse rated 250 V AC with 50 A interrupting capacity, 20 mm × 5 mm cylindrical body, pack of five

  • 5 A rating protects circuits from overload
  • Fast-acting glass element clears faults quickly
  • 50 A interrupt rating at 250 V AC handles short circuits
  • 20 mm × 5 mm cylindrical size fits standard holders
  • Pack of 5 gives ready spares for maintenance

5A Glass Fuse Pack

This pack contains five Eaton Bussmann S500-5-R glass fuses rated at 5 amps and 250 volts AC. They are designed for circuit protection in compatible holders and blocks. The cylindrical, non-rejection body fits standard 20mm by 5mm fuse clips. Each fuse is fast-acting and carries CE, CSA and UL certifications.

Interrupt Rating and Capacity

The fuses have an interrupt rating of 50A at 250V AC, providing protection for circuits where available fault current does not exceed that level. They are suitable for low-voltage applications requiring fast-acting overcurrent protection. The rating defines the maximum fault current the fuse can safely interrupt. Circuits with higher prospective short-circuit current require a different protection device.

20mm x 5mm Cylindrical Form Factor

The physical dimensions are 20mm length by 5mm diameter, matching the standard cartridge size for this fuse class. Compatibility depends on the fuse block or holder accepting this exact form factor. Verify that the equipment specifies this size before installation. The non-rejection design means it fits standard clips without a keyed feature.

Questions about this item

Will the 5 A 250 V AC fast-acting glass fuse work in my older HTB-series fuse block?

Yes, the S500-5-R is listed as compatible with HTB fuse block series and matches the 20 mm × 5 mm cylindrical size used in those holders.

How can I confirm the fuse is operating correctly after installation?

With power applied, measure voltage across the fuse; a reading near zero volts indicates the 5 A element is intact and conducting normally.

What comes in the pack and do I need to buy a fuse holder separately?

The pack contains five S500-5-R glass fuses; a compatible HTB-series fuse block or holder is not included and must be purchased separately if you do not already have one.
