Five glass cylinder fuses with metal end caps

Bussmann

Bussmann S500-160-R Glass Fuse 160mA 250V AC 35A 5 PK

SKU CH-HZ4W-DC8XQ

Pack of five fast-acting 20 mm glass fuses rated 160 mA at 250 V AC with a 35 A interrupt rating

  • Fast-acting protection clears faults quickly
  • 160 mA rating suits low-current circuits
  • 35 A interrupt rating handles high fault energy
  • 20 mm × 5 mm glass body fits standard holders
  • Pack of five provides ready spares

What this fuse is and who needs it

This pack contains five glass cartridge fuses rated at 160 mA and 250 V AC. They are designed for low-current circuit protection in equipment such as instruments, control boards and small appliances where a fast-acting device is required.

What it replaces and when the change makes sense

The fuses are direct equivalents for Bussmann GDB and S500 series, Littelfuse 217 and Mersen GSB parts. Swapping to this pack is worthwhile when existing fuses have blown or when a spare supply is needed for maintenance of compatible fuse blocks such as the HTB series.

What to verify on your hardware before ordering

Confirm that the circuit calls for a 20 mm by 5 mm cylindrical glass fuse with a 160 mA rating and a 35 A interrupting capacity at 250 V AC. The fuse is non-rejection style and single element, so the holder must accept that body format and the application must not require a time-delay characteristic.

Questions about this item

What fuse-block series accepts the 20 mm × 5 mm cylindrical glass body of this S500-160-R fuse?

The HTB series fuse blocks are compatible with the 20 mm long, 5 mm diameter glass body used on this fuse.

How is the fast-acting glass fuse installed, and what common mistake should be avoided?

Push the cylindrical fuse straight into the HTB fuse-block clips until fully seated; do not twist or force it, as the glass body can crack.

When should the 160 mA, 35 A interrupt-rated fuse be replaced?

Replace the fuse after it has blown, since it is a single-element, non-rejection type that cannot be reset.
