Glass Fuse 100mA 250V AC
The EATON BUSSMANN S506-100-R is a cylindrical glass fuse rated for 100 mA at 250 V AC with a 35 A interrupt rating. It suits technicians and engineers protecting low-current control circuits, instrumentation or small power supplies where a time-delay characteristic prevents nuisance opening during brief inrush. The 5-pack quantity supports bench stock or field service kits for repeated replacements.
Friction-fit installation in HTB blocks
The fuse uses a non-rejection body style measuring 20 mm long by 5 mm diameter, designed for compatible HTB series fuse blocks. Installation requires simple insertion into the clips; no tools or soldering are needed. The most common error is forcing the fuse into an undersized or mismatched holder, which can crack the glass body or leave a high-resistance contact that overheats under load.
Time-delay glass tube under sustained load
The single-element, time-delay construction tolerates temporary overloads above 100 mA without opening instantly, allowing equipment start-up transients to pass. Under a continuous fault the element melts cleanly and the 35 A interrupt rating at 250 V AC safely clears the circuit. The glass body lets you verify element status visually, while cURus, IMQ and MITI/JET 1641-31003-1005 recognition confirms compliance for installed equipment.

Questions about this item
How can I verify the S506-100-R fuse is working after installation?
The circuit should remain powered under normal load; the time-delay element tolerates brief surges without opening, while the 35A interrupt rating at 250V AC protects against sustained overcurrent.
What comes in the pack and what else is needed to use these fuses?
Five 20mm x 5mm glass cylindrical fuses are included; a compatible HTB-series fuse block must be purchased separately for mounting.
Which equivalent series matches the S506-100-R for a direct replacement?
The S506-100-R crosses to Bussmann GDC, Littelfuse 218 and Mersen GDG series; choose the series your existing fuse block or equipment specifies.
