What kind of fuse block is this?

[hovr]

Hi,
Attached photo is a fuse block I found inside a 12v panel box of a 2021 Caravel, I am trying to figure out the wiring but I am having hard time understand the connection inside the fuse block.
Some questions -
- What's the the name/brand of this fuse block?
- 1 and 2 are connected with fuse F1, same for 4 and 5(F2), 5 and 6(F3) right?
- What about the blue wire 3? Is it connected with C on top?
- Is 1 also connected with A, 2 with B, etc - the top row connected with ones on bottom row in the same column?
- What's the purpose of the 2 holes under D and E or above 7 and 8?
- 9 and 10 (yellow & red wires) are just about 8 inch long wire with open end, nothing connects to them. What's the purpose of them?

So basically this works like breadboard, connectors in same column are connected and fuse blades are used to connect between columns next to each other?

Thanks in advance!

That is a WAGO terminal block. Very similar to what we use at work. Those you have marked F should be jumpers, not fuses.

Looking at it, A-B-1-2 should all be connected together. C-3 together, 4-5-6 together and so on.

Thanks! So what's the purpose to have the A-G wired this way? I mean why not have the bottom row wires directly connect to the bus bar at top, the blue lines with F2 and F3 might need a separate bus bar, but it would be simpler than this right?

The wires that have jumpers to connect the blocks together make a very good junction and easy to troubleshoot. Just pull a jumper and you can separate the wires from each other without having loose wires hanging.

The others on the right that go straight through, I have no idea. I do know that kind of stuff happens when you leave engineers alone without adult supervision!

The distribution boxes are pre-made and this allows the Airstream tech the ability to connect the distribution box to the trailers wire harness. All the distribution boxes for the newer trailers are made the same way with the Din rail mounted WAGO block. The wires are different Based on the model.

I thought I'd tag on to this thread, since the question is related to the same terminal block. In my 2018 20 foot Bambi, this terminal block contains the fuse for my LPG detector. The fuse block is a lever type, and when I pulled it up the fuse legs are visible there. I've put some effort into searching for information about how to open this thing to put in a replacement fuse, but I've struck out on that front. I have an email in to Eaton, the manufacturer, but no reply yet. I will see if someone at Airstream can provide info, but thought I'd see if I could get an answer here first.

Several pix are attached. The schematic is the starting point, which convinced me that this was the correct fuse. The remaining pix are of the fuse block on the DIN rail, and then opened up. I couldn't figure it out in place (it's a hard place to get hands and lights to), so finally I removed it. Even in my hand, I can't figure out how to non-destructively open it.

Any help out there? Thanks.
