Five glass cylindrical fuses with metal end caps

Bussmann

Bussmann S506-63-R Glass Fuse 63mA 250V 35A 5pk

SKU CH-W2N2-6G2MV

Time-delay S506-63-R glass fuse rated 63 mA at 250 V AC with a 35 A interrupt rating, supplied in a pack of five

  • Time-delay operation protects circuits from nuisance trips
  • 63 mA rating suits low-current precision applications
  • 35 A interrupt rating at 250 V AC handles fault currents safely
  • 20 mm x 5 mm cylindrical glass body fits standard fuse holders
  • Pack of five provides convenient spares for maintenance

Bussmann S506 63mA Glass Fuse Pack

This pack contains five Bussmann S506 series glass fuses rated at 63 milliamps and 250 volts AC. Each fuse has a cylindrical body measuring 20 millimetres long by 5 millimetres in diameter. The time-delay characteristic suits circuits with brief inrush currents. They carry a 35 ampere interrupt rating at 250 volts AC.

Service technicians and hobbyists maintaining

These fuses fit equipment that specifies a 20mm x 5mm glass cartridge with a 63mA time-delay rating. Builders who need a different current rating, a fast-acting response or a ceramic body should look at other parts. The non-rejection design does not suit holders that require a rejection feature. Installers needing agency marks beyond cURus, IMQ and MITI/JET1641-31003-1005 must verify suitability separately.

63mA time-delay rating with 35A interrupt capacity

The decisive specification is the 63 milliampere time-delay rating combined with a 35 ampere interrupt rating at 250 volts AC. This pairing determines whether the fuse will hold harmless transients and clear faults safely in the target circuit. Cross-reference equivalents include Bussmann GDC, Littelfuse 218 and Mersen GDG series. Compatible fuse blocks include the HTB series.

Questions about this item

Will the 20 mm length and 5 mm diameter fit my existing fuse holder?

The fuse measures 20 mm long and 5 mm in diameter, matching the standard cylindrical glass body used in many 5×20 mm holders.

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

Insert each fuse straight into the clips without twisting; the glass body can crack if forced at an angle.

What should I check when replacing a blown fuse from this 5-pack?

Verify the replacement is also a 63 mA, 250 V AC time-delay fuse with a 35 A interrupt rating.
