2022 release. They hold loads up to 32 A perfectly. Do not listen to smart people who have all spring-type terminals from Wago, including very good Chinese-made copies on them. Therefore, they advise them to put only on lighting. These terminals are original, so it is worth considering 2 points: 1) Despite the fact that they are spring-loaded, although the springs are of high quality, it is not worth putting them in maintenance-free boxes / hard-to-reach places. 2) Choose the right protection devices. I recommend limiting machine up to 25A.
