Five cylindrical glass fuses with metal end caps

Bussmann

Bussmann S500-500-R Glass Fuse 500mA 250V 35A 5pk

SKU CH-ZZ76-1BBX0

A pack of five 20 mm glass fuses rated at 500 mA and 250 V AC with a 35 A interrupt rating

  • Fast-acting protection clears faults quickly
  • 35 A interrupt rating at 250 V AC handles high fault currents
  • 500 mA rating suits low-current circuits
  • 20 mm x 5 mm glass body fits standard holders
  • Pack of five provides ready spares

500 mA glass fuse for low-current circuits

This pack contains five EATON BUSSMANN S500-500-R fast-acting glass fuses rated at 500 mA and 250 V AC. They suit control boards, instrumentation and similar low-current equipment where a 20 mm by 5 mm cylindrical fuse is specified.

Check the holder and rating before ordering

Verify that your fuse block accepts a 20 mm long, 5 mm diameter cylindrical body and that the circuit requires a 500 mA fast-acting fuse with a 35 A interrupt rating at 250 V AC. The fuses are non-rejection type and compatible with HTB series blocks. They are not suitable for circuits needing a higher current rating or a time-delay characteristic.

Thermals noise and power draw in normal use

As passive over-current devices the fuses generate no audible noise and draw no power themselves. Under normal load they run at ambient temperature; only during a fault event will the element melt to interrupt up to 35 A at 250 V AC. The glass body allows visual confirmation of a blown element.

Questions about this item

What comes in the pack and is a fuse holder included?

The pack contains five glass fuses; a compatible HTB-series fuse block must be purchased separately.

How do I choose between the listed equivalent series such as GDB, 217, GSB and S500?

They are cross-references for the same 500 mA 250 V AC fast-acting 20 mm × 5 mm glass fuse; select the series your existing holder or bill of materials specifies.

What does the 35 A interrupt rating mean when the fuse is installed in a 250 V AC circuit?

It indicates the fuse can safely break a fault current of up to 35 A at 250 V AC without rupturing the glass body.
