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.
