Adding 3amp fuse

HU-404036269
14 days ago

Hi all I have what should be a simple question. I want to add a 3amp fuse to my transformer 24v output line that runs the zone board in my Lennox electric furnace. None currently there. So my question is concerning the fuse volt rating. Is the correct fuse a 3amp 24 volt fuse or just a regular 3amp 12v blade style fuse like you would find in your car. The same goes for the fuse holder, something special?
Thank you in advance for any guidance.
