What is this style of MCB called? (See attached image)

Bita_dis_bita_dat

I'm trying to find info on our home circuit board. I know this is an old-school setup and I will be upgrading the circuit board, however, for now, I just need to swap a fuse but as these aren't the modern style I'm finding it hard to search for a guide. Can someone help me identify this style of circuit board so I have the right keywords to search? The circuit breakers sit down on prongs that are wired to rather than modern ones that prongs are at back and you clip in. Also if someone has a comprehensive guide on removing the circuit breakers (a youtube vid preferably).

Thanks.

You don’t know what you are at.

electricity kills and causes fires

only a rec is permitted to work on fuse boards.

time for the professionals

I think it's illegal for you even to have removed the cover let alone work on the board.
