So I know it may be a basic question but hear me out. These are the specs for the transformer I would like to buy.

To add a fuse to the primary coil I would do 16VA/240V which gives 0.06A. Does that mean I need to get a 100mA fuse?

Yes, a 100 mA fuse should do the job.

There are fast (F) and slow (T) fuses, I would start with a fast fuse and see how that works out. If the fuse would sometimes blow when the transformer is connected to AC mains then try again with a slow fuse.

  • \$\begingroup\$ Thank you Bimpelrekkie. Should this be the correct one? Does it correspond to the specification of the transformer? uk.rs-online.com/web/p/cartridge-fuses/0563582 \$\endgroup\$ – M2T156 Feb 13 '19 at 8:22
  • \$\begingroup\$ There is no need to have the fuse "correspond to the specification of the transformer". A fuse is a fuse. This is a slow fuse. It will do the job. \$\endgroup\$ – Bimpelrekkie Feb 13 '19 at 8:25
  • \$\begingroup\$ Okay that's great so that it will work fine then? Should I order it? \$\endgroup\$ – M2T156 Feb 13 '19 at 8:27
  • \$\begingroup\$ @M2T156 It will work just fine. Make sure you have a proper fuse holder. Keep in mind that transformers tend to draw large amounts of current for 3-4 grid periods, when connected. So if the fuse blows, just buy a 200 mA fuse. \$\endgroup\$ – thece Feb 13 '19 at 8:44
  • \$\begingroup\$ The fuse has a current of 35A is that you are talking about the surge current? \$\endgroup\$ – M2T156 Feb 13 '19 at 9:00
