Where in Europe are they used?  Apparently not in Italy, Poland, Germany, or UK, according to our FAEs.

Funny you even mentioned Germany, you realize Wago is a German company, right?

I did not notice that Wago was a German company, but lots of companies make products that are not sold or used in their home markets.

We specified wago connectors for a high vibration enviroment (gas compressor & motor chain junction box's mounted on the skid) about fifteen years ago.

Both the Dutch and the German customers were very sceptical about the "screwless connections" within our junction box's. The germans came around, when we pointed out that they are mage by a German company. The Dutch gas company came on board when their service engineers gave them the thumbs up.
They do not work loose, so they didn't have to go around checking for loose terminals in the anual shutdown/ routine maintenance schedules. Faults due to loose terminals vertually disappeared. Wago make them in all sizes from PCB mounted all the way up to 35mmsq din rail mounted, sold wire or stranded.
I do not work for wago, just a satisfied customer.

Or you can just call and speak with the company.  It is a great outfit.

They're used extensively in both residential and industrial applications.

The very fact they are used so extensively in high-vibration environments is one reason I smirk a little when people tell me about them easily falling off.
