400V CEE power distributor, with MCB, RCD and EMI/RFI filtering?

[collner]

I need a 400V 16A CEE power outlet that is somewhat mobile, at least I should be able to change its location when disconnected from power. I do have the proper CEE extension cable with 2,5 mm2 cables, but the house outlet have an antique fuse box, and no RCD as far as I can see.

I find many different kinds of power distributors that are built like inline units so that they do not require installation. These commonly have both MCB and RCD.

However, I can't find any that also have EMI/RFI-filter, neither can I find inline EMI/RFI-filter products for three phase 400V 16A (non installation product, inline CEE to CEE)

Maybe someone here know if such product exist?

Example of typical inline CEE 400V distributor box:
