Although the arc chutes are not functional with the case opened for vision, but it would be interesting to see the trip action in slow motion video. Or if the case was built complete as a teaching aid and was built with a clear case. Then a slow motion video would give us a great view of the arc flash being extinguished/or lessened in the channels.

Will the bi-metal strip re-shape after being curved or need to replace?

теперь можно снять короткое замыкание, чтобы сработал электромагнит,
можно от сварочника 😉

Hello, can anyone tell if it is completely safe to use these CNC brand circuit breakers? I'm going to remodel the electrical panel in my house and I wanted to use 1P+N, all from the same brand. Do you recommend CNC?
