Hi, a three-phase smart protector, it is a circuit that constantly monitors the power supply from where it is connected, if a phase is missing or the phase rotation changes, the voltage drops in any of the phases or rises, in any of these cases disconnects the circuit downstream of it. but it would be useful only if the power of your house were three-phase and for the voltage that is designed, if not, you should look for a single-phase one.
If my house has three-phase. So I need one That is three-phase, right? Is there for different consumptions? Could you recommend a brand that is good? Thank you!
I mean, what I want is that when the power goes out, a lot or low electricity comes, the electrical appliances in the house are not damaged .... Do I have to put on a smart protector or something else?
Excuse me but I am not very knowledgeable in the subject and as what they offer me is so expensive (intelligent three-phase protector) I would like to be sure. Thank you!
