There should be a tab close to base in which to insert a screwdriver. This will release it from the rail.

To release connectors from the blue ground bus terminal you can use a screwdriver. You just need to put the screwdriver in the corresponding hole and turn it firmly counter clockwise. I’m not sure whether it’s supposed to be phillps or flat; I’ve used both with equal success. I’m not sure how to remove the bus from the rail; I’ve never tried that.

I’ve read that you can use regular blade style fuses in that fuse bar, but I’ve never tried that myself.

You have “Din Rail Terminal Blocks”. Search that and you’ll find all sorts of designs and colors. The ones in your image appear to be snap ons.

When purchasing assure that they are rated for the load you plan to apply.

You have a mostly clean install.

Only critique is the large red wire (supplying power to the terminal block) is installed with too tight of a radius. The wire should be secured in a straight line as it connects to terminal block. This one is putting strain on the wire to lug crimp. It will lead to eventual failure.
