Yes but I want a screen and breaker per 4s. These are for my mobile 12v system in my work truck.

If you're using Victron Lynx, they added a T-Class fuse holder-with-busbars to their product line.

Lynx Class-T Power In - Victron Energy
The Lynx Class-T Power In connects and fuses up to two strings of Lithium batteries. It features a positive and negative busbar, and connections for two...

First time it's been seen in the wild I think. Two fuse holders, two battery inputs. One thing to note it's an m10 sizing for the terminals, and would need to work in conjunction with an m10 distributor unless maybe you did some drilling.If you're using Victron Lynx, they added a T-Class fuse holder-with-busbars to their product line.

Yep, both the Lynx Distributor and Lynx Power In come in both M8 and M10 for the busbar linkage, it seems the Class-T Power In only comes in M10, it's something to take note of.
It comes at just below Euro 200,- not cheap ... but I've looked at Class-T fuse holders, Euro 45,- each, and then you need some lugs to go from the holder to a busbar and so on.
However, a Class-T in the battery itself has the benefit of being as close to the cells as possible.
So I'm conflicted at the moment.

I was expecting four inputs for some reason but now I see if you had two 400A fuses now you are at 800A theoretical on a 1000A rated bus.
I think it's nice to have as an available option, but like you said I think best practice is having the fuse/breaker closer to the batteries. If your runs are short maybe?

The Lynx Class T would be best used when outputting to a pair of inverters, a Class T to each inverter. Take my system for example, the Lynx below the wiring trough has all power from the battery bank and charge controllers to it, then it is split off to each inverter. In the wiring trough, there is a Class T 250A for each inverter. This would eliminate having a Class T in the wiring trough.
If it is $200 though, it isn't price competitive. I just ordered some Class T's from Don Rowe and the cost for each Class T holder with a 250A fuse is $79.99 each. A Class T by itself is $59.99.

Personally, I would use a Class T for each inverter.
Plenty of battery power ahead of the Class T's in my system. Each battery has a Class T 175A and I have 4 batteries to a solid copper busbar which has 4/0 battery cable to the ABB breaker. The ABB shunt trip breaker is set to 500A on the Batrium, 4/0 battery cable in and out. Each inverter circuit is protected by a 250A Class T fuse, 2/0 battery cable.

Right, class t for batteries and then megafuses in the distributor(s) for the inverters and charge controllers.
Which models are you going to run in 3 phase?
48/5000, 230V

It will be interesting to see how much Amy will charge for a custom face plate. Shipping shouldn't be too bad.

I should know today on the face change and two BMS mounts in the box.

You might not hear as much from me, I'll be busy. From Luyan, shipped out March 13th. Fast boat, about 35 days.

So can the Class-T Lynx Power In only handle 2 batteries where the regular Lynx Power In can handle 4 batteries?

Yes. The standard lynx power in has 4 pairs of regular bus connections, no fusing.

When ordering cases WITHOUT Cells (when you have your own & want to install into cases) it is VERY Important to account for the different cells terminal spaces. Even with EVE LF280* Cells, the terminals may be either tapped holes, welded studs or the new double hole mounts. LF280's have their terminals closer to the middle unlike the N & K versions.
As Luyuan/Amy are supplying bus bars (flexible Laminated copper for dbl terminal, Copper Wire Mesh, or Solid tinned copper) the required length will be different, "most especially" on the X-BAR that crosses from one side to the other.
Of course the various Brands & Models/Revisions CATL, Lishen, Gotion (ad infinitum) all vary.
