Thank you very much for the reply. I tell you that I have a 25 amp contactor through which all the electricity in the house passes, that is to say that I have
first general thermal
segund circuit breaker
3rd RBC sitel high and low protector
fourth 25 amper schneider contactor
From there I go to the thermals of each circuit.
Do you decide that with those 25 amper the contactor is enough to power the entire house?
Check the total consumption of the property, since the contactor must support the load of the circuits that start from it. The approach to distribution, General Thermal, Circuit Breaker, Protector that feeds the contactor coil, and the contactor feeds the terminal circuits is fine.
Very good clarification Carlos! How can I calculate the total consumption of the house?
From the contactor I have 5 circuits that come out: two of 16amper (plugs throughout the house, divided into 2), one of 10 amper for the lights, one of 20 amper for the air conditioning and another of 25 amper that goes to another box with thermal for the laundry
Yes ... I know, it has a 10mm cable from the meter to the main key, it is quite high compared to the standard 32 amper, but I don't think it's a problem (correct me if I'm wrong, I'm not a professional on the subject )
If all the connections are made with 10 mm², it would be fine, but the protector requires protection, just as the general thermal is armed, it should not exceed 25A but it is sure that it is insufficient so that a special connection must be made incorporating another thermal
The last thing is not clear to me. Do you decide to remove the contactor and replace it with a 25 amper termination before the protector? I read that a contactor was needed for the RBC sitel protectors
No ... the contactor is something else and if the simultaneous load exceeds 25A, if or if you have to put it
What I said is that the protector comes for 25A and a 25A contactor makes no sense. The contactor is used when the maximum capacity of the protector is exceeded. In your case you should use it but it should be 40 or more
very good scheme! I already have a 10amper end for the light circuit, under the contactor. Could you use that to protect the RBC sitel protector? What risk is there that does not have thermal protection?
Great! it occurred to me that perhaps it would be good to put a high and low protector with more amperage, such as a Gralt brand, which has a maximum current of 63 amper (https://articulo.mercadolibre.com.ar/MLA-701055323-protector- de-voltage-high-and-low-63a-voltimetro-monophasic-_JM # D [S: ADV, L: VIPCORE_RECOMMENDED, V: 4, I: 1kaXNwYXRjaGVyLTIxOHwtNDIxNjc1ODkwMDc1NzA4MTAzMw == high =), C = 0.00 a00 high =) low that exceeds 40 amper of the general thermal, so you would not need the dedicated thermal protector, right?
Thank you so much everyone! They really are geniuses! I admire the exchange we always have, which leads to the best solutions
