For my project I need a lot of terminals, like atleat 16-20 (2 Pins). Currently I am using WAGO 237-102 with 16amp rated because cheap and small but I would love to go smaller. Searching around I found 2 row terminal blocks and because I would like to get smaller I was thinking about using a big one like 2×10 something like a WAGO 252-110 but in the Datasheet they only state a current rating of 2A.

My question would be : Are these 2A are for the complete connector of per pin ? Another question : Do you have another idea on how to connect my cables ? (load 12V with 500mA ea – 2.5 mm²)
