This is not from Wago! This looks like an intentional scam as they simply prefixed the Wago part numbers with an A to confuse customers. They are not UL listed so DO NOT use them in the US. They are not CE approved so DO NOT use them in Europe. I couldn't find any agency approval for this at all, which is highly unusual for an electrical connector. It appears to be a deliberately misleading fake. Find Wago 221 Series Lever Nut Connectors.
