Hi,
I'd like to switch on/off an electric element that's connected between 2 phases of 3phase system. Voltage between those phases is 400V.
What's the highest voltage that can be connected to the output of Shelly1? Since power of that element is 800W I don't expect current to be the problem but high voltage could.
Would it be wise to connect that element directly to the Shelly1 or should I buy additional relay for that?
Thanks!
