Bussmann S501-10-R Fast Acting Fuse

The Bussmann S501-10-R is a fast-acting cylindrical fuse rated at 10A and 250V AC for line protection. It features a ceramic body measuring 20mm in length and 5mm in diameter with a 1.5 kA interrupt rating. The non-indicating, single-element design comes in a package quantity of five. It carries CE, CSA and UL certifications.

Suits 10A 250V AC circuits needing fast-acting

This fuse suits applications requiring fast-acting response on 250V AC lines with a 10A rating. It fits holders compatible with the HTB fuse block series and matches the 20mm x 5mm cylindrical form factor. Buyers needing a visual indication of fuse status should look elsewhere as this model is non-indicating. Circuits demanding a higher interrupt rating or a different voltage rating also require a different part.

Simple cylindrical installation in compatible

Installation consists of inserting the 20mm x 5mm ceramic body into a compatible fuse block such as the HTB series. The non-rejection design allows fitment without a keyed holder. What usually goes wrong is using a fuse with the wrong ampere rating or voltage rating for the circuit. Ensure the 10A and 250V AC ratings match the system requirements before fitting.
