EATON BUSSMANN S505 Ceramic Fuse 1A 250V
This pack contains five EATON BUSSMANN S505 series ceramic fuses rated at 1 ampere and 250 volts AC. Each fuse has a cylindrical body measuring 20 mm long and 5 mm in diameter. The time-delay characteristic helps absorb temporary inrush currents without nuisance opening. They are designed for line protection in equipment that uses 5 x 20 mm fuse holders.
Suits repair of appliances
These fuses suit technicians servicing devices specified for the S505, 215 or GSF series with a 1 A time-delay rating. They are not for circuits needing a higher interrupt rating than 1.5 kA at 250 V AC. They are not for applications requiring indicating or rejection-type fuses. Buyers needing a different current rating or a fast-acting characteristic should look at other parts.
Interrupt rating 1.5 kA at 250 V AC decides fit
The single specification that decides whether this is the right part is the interrupt rating of 1.5 kA at 250 V AC. The fuse must be able to clear the maximum prospective fault current of the circuit it protects. If the installation demands a higher breaking capacity, this fuse is not suitable. Always verify the equipment’s required interrupt rating before fitting.

Questions about this item
Does the 1.5 kA interrupt rating handle sustained overloads without overheating the ceramic body?
The 1.5 kA rating at 250 V AC is the maximum prospective short-circuit current the fuse can safely interrupt; the ceramic body and time-delay element are designed to contain that energy without external heat damage.
Which fuse holder series accepts the 20 mm × 5 mm cylindrical body of these S505 fuses?
The compatible fuse block series is HTB, which is built for the 20 mm length and 5 mm diameter of this S505 cartridge.
Can the S505 replace a Littelfuse 215 or Mersen GSF in existing equipment?
Yes, the S505 is listed as equivalent to the Littelfuse 215 series and Mersen GSF series, so it fits the same holders and carries the same 1 A, 250 V AC, time-delay rating.
