Glass fuse for low-current circuits
The Bussmann S506-50-R is a cylindrical glass fuse rated at 50 mA and 250 V AC with a 35 A interrupt rating. It suits equipment that needs reliable overcurrent protection on low-current lines such as control boards, instrumentation or small power supplies.
Time-delay glass body fits standard 20 mm clips
The 20 mm by 5 mm glass tube is non-rejection and single-element, so it slides into common HTB-series fuse blocks without a special keyed holder. Time-delay action tolerates brief inrush surges while still opening on sustained overloads, reducing nuisance replacements in daily service.
Direct replacement for GDC, 218 and GDG series
This five-pack crosses to Bussmann GDC, Littelfuse 218 and Mersen GDG fuses, letting maintenance teams consolidate stock around one part number. The jump is worth it when existing fast-acting fuses blow on start-up transients and a time-delay characteristic is needed instead.

Questions about this item
What does the 35 A interrupt rating at 250 V AC mean for this fuse?
It means the fuse can safely break a fault current up to 35 amps at 250 volts AC without rupturing.
What fuse block series does the 20 mm x 5 mm cylindrical glass body fit?
The S506 series fuse fits compatible HTB fuse blocks designed for 20 mm length and 5 mm diameter cartridges.
How do I install these time-delay glass fuses without damaging the element?
Insert each fuse straight into the HTB block clips; do not twist or force the glass body, which can crack the single element inside.
