Looks like a standard 20mm glass fuse. Some wholesalers will stick them or else any online electronics supplier like RS

Fuses dont 'blow' like that without reason. Looks like the effect of a short circuit!

thanks Dave... just curious what difference is and why they would be in glass

They are glass so you can see whether or not they are intact. However glass fuses are only suitable for low levels of fault current as the glass cannot contain much energy.

The rating of the fuse will be marked on one of the end caps, followed by a 'F' or 'T', standing for fast or slow( time) blow respectively. Be sure to fit the right type.
That fuse looks like it's been blown by a short circuit or large overload, so do some fault finding before just trying another fuse. Things like relay contacts can be irreparably damaged if subjected to successive shocks like this.

5x20mm fuses come in both glass (LBC = low breaking capacity) and sand-filled ceramic (HBC = high breaking capacity) body versions. The glass type is standard within equipment especially for ELV circuits where the short-circuit current might only be a few amps. It's OK to replace an LBC with an HBC of the same rating and speed, but obviously not the other way round.

With PCB markings take care not to confuse the component identifier (e.g. F2 = fuse No. 2) with the rating (e.g. F2A = 2A fast-blow.) The marking 'F1 T2.5AH' would indicate that fuse No. 1 is an HRC 2.5A slow-blow type.

FWIW the speed letters are German. F = flink = nimble, T = träge = sluggish. There are also M (medium) and FF (ultra rapid) types but they are much less common.
