How to repair: Tetrapolar or bipolar

Hello partners
Can a tetrapolar differential circuit breaker be used in a single phase line (phase and neutral)?

Thank you


1 Proposed Solution

SOLUTION ACCEPTED
Yes, no problem. It must be connected only to one of the poles and to the neutral.
It can also be used in a three-phase circuit without neutral.

    Thanks Ennio !!! They gave me a Schneider differential, when I saw it I thought it was not going to help me. And since these I ask you, can you use the four connections and make two independent circuits? Thank you

    If right.
    The only thing is that both circuits must return through the same neutral.
    What yes, when it operates, you will not know which of the two circuits is the one that made it operate. You would have to do tests to find out in which the earth discharge occurred.

    They can be one, two or three circuits with the same neutral.
    It can also be used on an engine, which has no neutral.

    The idea is like this, a circuit for the house and another for the bottom, but at the bottom it would put a more sensitive circuit breaker (this one is 30th and it would put one of 10th at the bottom, laundry and grill) There was a problem and I leave all the house without light, I think this would be a possible solution for the future. Do you see it viable?

    My opinion is that it must be 30ma. How is a wet sector, could jump very often the 10th ..
    If you are going to have two differentials, it is preferable that they remain independent.

    When I referred to connecting only one of the poles, it is so that one phase does not connect to one pole and the output connects to the other pole and the output of the latter to the third pole.

    To see input = phase and neutral to two of the four terminals, output circuit of the house. The cable that goes to the bottom, can't I get it from the other two terminals?

    The laundry and grill circuit, you don't have it separated .. ??

    They are separated but with a single circuit breaker. The issue is that they went on vacation, there was a problem in the background and left the whole house without light. For that reason I wanted to put together a sectional board at the bottom and a more sensitive circuit breaker.

    If they are separated with thermomagnetic, you can set a differential to that circuit.

    Ok Ok There is a general circuit breaker and each circuit lights, sockets and bottom with independent thermal

    You would have to separate so that the laundry circuit does not go through the existing differential.

    I wanted to take advantage of the tetrapolar, but it wouldn't be ideal. I will continue with the original idea. Sectional board at the bottom and circuit breaker exclusive for that part. Thank you very much for your help.

    How I told you, one of 10th for a wet sector, will be very sensitive.
    It is my appreciation.

    OK I will follow your advice Thank you
