Displays and Projectors : Fused switching transformer ?

Fused switching transformer ?

Hii…

Does anyone knows something about BCK switching transformers like this one, with built in fuses?

In the pdf PSU circuit diagram, theres no fuse, but another coil in series with TB901 primary neither.

What do u think?

Thanks!

I didn't find the right solution from the Internet.
