Bussmann

Bussmann S505-2-R Ceramic Fuse 2A 250V 1.5kA 5PK line protection

SKU CH-8M9D-9Q5TW

Pack of five 2 A ceramic time-delay fuses rated 250 V AC with a 1.5 kA interrupt rating

  • 2 A rating protects circuits from overload
  • Time-delay characteristic tolerates brief inrush current
  • 5 kA interrupt rating breaks fault current safely
  • Ceramic body withstands high temperature during operation
  • Pack of five fuses supports multiple installations

Bussmann S505-2-R 2A Ceramic Fuse Pack

This pack contains five Bussmann S505-2-R ceramic fuses rated at 2A and 250V AC with a 1.5kA interrupt rating. They are time-delay, non-indicating fuses designed for line protection in compatible circuits. The cylindrical ceramic body measures 20mm long by 5mm in diameter. Each fuse meets BSI, CCC, CSA, IMQ, SEMKO, UL and VDE standards.

Suitable for 5mm x 20mm fuse holders needing

These fuses suit applications requiring a 2A time-delay ceramic fuse in the standard 5mm by 20mm form factor. They are not for circuits needing a faster-acting fuse characteristic or a visual indication that the element has blown. Buyers who need a rejection-style fuse or a different ampere rating should look at other series.

2A 250V AC rating with 1.5kA interrupt capacity

The decisive specification is the 2A rating at 250V AC combined with a 1.5kA interrupting capacity at that voltage. This determines whether the fuse can safely clear a fault in your specific circuit. Verify that your equipment calls for exactly this current and interrupt rating before fitting.

Questions about this item

What is the interrupt rating of the S505-2-R fuse and what does it limit?

The interrupt rating is 1.5 kA at 250 V AC, meaning the fuse can safely break a fault current up to 1.5 kiloamps without rupturing.

What are the physical dimensions needed for the fuse holder or block?

The cylindrical body measures 20 mm long by 5 mm diameter, so the holder must accept a 5 mm x 20 mm cartridge.
