Where do i get one of these please ?

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.

Never knew that's where the speed letters came from. I always thought it was T=Time lag and F = Fast.

if emergency can use 5a fusewire to link between

That is a very bad and potentially quite dangerous idea.

After all that ended up being a dodgy ‘Neostat’
