What this fuse does
The Bussmann S506-3.15-R is a glass-bodied, cylindrical fuse rated at 3.15 A and 250 V AC with a time-delay characteristic. It is designed for low-voltage circuit protection in equipment that needs a brief inrush tolerance before opening. The pack contains five fuses.
Interrupt rating decides fit
The fuse carries an interrupt rating of 35 A at 250 V AC, meaning it can safely break a fault current up to that level without rupturing. If the prospective short-circuit current in your circuit exceeds 35 A, this fuse is not adequate and a higher-rated type must be chosen.
Simple push-in installation
Each fuse measures 20 mm long by 5 mm diameter and fits standard 5 × 20 mm fuse holders or compatible blocks such as the HTB series. The non-rejection body allows insertion either way round, but verify the holder clips make firm contact; loose clips are the most common cause of nuisance heating.

Questions about this item
What does the 3.15 A rating mean when the fuse is installed in a circuit?
It is the continuous current the fuse will carry without opening; sustained current above this value will eventually cause the element to melt.
What does the 35 A at 250 V AC interrupt rating cap in practice?
It limits the maximum prospective short-circuit current the fuse can safely break at 250 V AC to 35 A.
What physical dimensions does the fuse need to fit a holder?
The cylindrical glass body measures 20 mm long by 5 mm diameter.
