Hi all,

I bought a solar fuse/switch on eBay named AED type 4P20A.
Now I'm wondering how too wiring it up.

https://www.ebay.nl/i/302235175890

Inside it there are three bridges soo all the incoming are connected together and on the outgoing side there is one bridge.
 
Image of it? generally there is a special wiring for 1000VDC and one for less than like 700 or something.

I guess above is 4pole?
 
Yes it is 4 poles.

On many of those you do it like this:

But if of course depends on the switch. Atleast mine are wired kind of like this. For support of 1000VDC

I have seen this kind of setup before on the sides of 3 pole breakers, why would you loop through it and then come back out?
 
Higher voltage tollerance. Ie larger disconnect gap inside
 
What voltage and current are you expecting to switch with this?

High voltage DC gets special (and dangerous!)
