I justify with references to GOSTs that SFT modular switches from Hager can be switched under load. The fact is that in the previous video about these switches, I confidently said that SFT switches can only be switched without load, as a technical consultant from Hager told me, but since the viewers corrected me and explained that, on the contrary, you can switch, since the switch's use category is indicated in the catalog as AC-22A, which means that it can switch an active-inductive load and can also be switched even under a slight overload. See the video for details. https://vk.com/ehlektrik - I recommend the #1 community on electrical engineering on VKontakte! https://vk.com/electron.kolomna - GOST+ team Electrical installation services in Moscow and the region Forum: http://ceshka.ru/forum/ Subscribe to the video channel: http://www.youtube.com/user/ceshkaru?...
