Ceramic Fuse 1.60A 250V
The Bussmann S505-1.6-R is a 1.60 amp ceramic fuse rated for 250 volts AC with a 1.5 kA interrupt rating. It suits technicians and maintenance teams needing reliable overcurrent protection for control circuits and small equipment. The time-delay characteristic handles brief inrush currents without nuisance opening. Each pack contains five fuses for stock replenishment.
Thermal and Power Behaviour
The ceramic body withstands the heat generated during a fault interruption up to the rated 1.5 kA at 250V AC. In normal operation the fuse runs cool and silent, adding negligible resistance to the circuit. No active cooling or noise consideration is required for this passive component. The time-delay element tolerates temporary overloads while still clearing sustained faults.
5 × 20 mm Cylindrical Fit
This fuse measures 20 mm long by 5 mm diameter and fits standard 5 × 20 mm fuse holders such as the HTB series. It is not a rejection-type fuse, so it will not suit holders that require a keyed or high-break-capacity cartridge. Buyers needing a different diameter, length, or indicating feature must select another part number.
Highlights
- Time-delay protection prevents nuisance trips
- 5 kA interrupt rating at 250 V AC
- Ceramic body withstands high temperatures
- 5 fuses per pack for multiple replacements
- UL, CSA, VDE and other safety approvals

Questions about this item
How do I install the 20 mm × 5 mm cylindrical fuse into an HTB fuse block, and what step is often missed?
Align the fuse ends with the HTB block clips and press straight in until both caps seat fully; the step often missed is verifying that each cap clicks into the clip so the 1.60 A time-delay element makes solid contact.
What maintenance or replacement will the 1.60 A 250 V AC ceramic fuse need later?
The fuse is single-element and non-replaceable; after it interrupts a fault at 1.5 kA you simply discard the blown unit and fit a new fuse from the 5-pack.
What limit appears first when the fuse runs continuously at its 1.60 A rating?
The time-delay characteristic allows brief overloads, but sustained current at or above 1.60 A will cause the element to melt and open the circuit, which is the intended protective limit.
