Ceramic Fuses

[James]

Can you use these T4 250V ceramic fuses in a WPC-95 for the GI string?

is it 20mm lenght or 32mm you need?

I found rs components have tons of fuses - here are 4A 20mm https://uk.rs-online.com/web/c/fuse...d-dimensions=4294812480,4294797950,4294773652

fuse speed ratings explained here - https://www.swe-check.com.au/pages/learn_fuse_speed.php
T, TT or @ rating for slow blow

RS is my go-to on fuses and components as since they dropped the min spend for free postage the price is great if you need stuff and you are in for the long game given you generally need to by in multiples of 5 or 10.

Regarding the ceramic Vs glass. My old man, who knows more about these things then I ever will, has assured me that as long as the fuses have the same rating the difference is that ceramic are designed to self contain and glass are to be viewable.

If a ceramic fuse blows the casing should remain intact and never enable anything to escape. A glass fuse does not have to meet the same requirements.

The advantage of glass in this hobby is we can see what's cooked.
