Five cylindrical glass fuses with metal end caps

Bussmann

Bussmann S500-10-R Glass Fuse 10A 250V AC 100A Interrupt 5 Pack

SKU CH-YWCT-WZJQG

Pack of five fast-acting glass fuses rated 10 A at 250 V AC with a 100 A interrupt rating

  • Fast-acting protection clears faults quickly
  • 10 A rating suits low-current circuits
  • 100 A interrupt capacity at 250 V AC
  • Glass body allows visual inspection of element
  • Pack of five provides ready spares

Purpose and fit

This pack contains five glass-tube fuses rated at 10 amps and 250 volts AC with a 100-amp interrupt rating. They suit technicians and maintenance teams who need fast-acting, non-rejection cartridge fuses for control circuits, instrumentation or small-appliance protection.

Build and connections

Each fuse has a cylindrical glass body measuring 20 mm long by 5 mm in diameter and follows the S500 series form factor. The non-rejection design allows direct insertion into compatible HTB-series fuse blocks without a keyed holder, simplifying replacement in panels that accept this standard size.

Upgrade context

These fuses cross-reference to Bussmann GDB, Littelfuse 217 and Mersen GSB equivalents, so they replace those series directly when the same electrical ratings and physical dimensions are required. The jump is worthwhile when existing holders accept the 20-by-5 mm format and the application demands a fast-acting, glass-body fuse with UL, CSA and CE compliance.

Questions about this item

What does the 100 A interrupt rating at 250 V AC mean for the S500-10-R fuse?

The fuse can safely break a fault current of up to 100 A on a 250 V AC circuit without rupturing.

What are the exact body dimensions of the S500-10-R glass fuse?

The cylindrical body measures 20 mm long and 5 mm in diameter.

How is the S500-10-R fuse installed and what common mistake should be avoided?

Insert the fuse into a compatible HTB-series fuse block; do not force it into a rejection-type holder because this is a non-rejection fuse.
