Contactor/relay - Switching off the power in the flat via GSM - Satel

Hello esteemed colleagues.
Let me start by saying that fellow electricians have rated me as a quarter electrician .

I am at the stage of building my dream flat and due to the fact that I am deciding on a satel control panel at the distributor, I dreamt of switching off the electricity in the flat via a programmable output in the control panel.

I would like to feed the 3 phases from the riser into a contactor (65A) in the distribution board and from there into the circuit. I would like to control the contactor with a 12v/230v relay and control it from the control panel.

I would like to control the contactor with a 12v/230v relay and control it from the control panel.

Am I right in thinking that a contactor and relay is the key to making this work? I have chosen an off-brand contactor because I don't know which one to choose, because it's cheap and I don't intend to use it often. The contactor has a 230V coil, so the relay is 12VDC-230V (the satellite has a 12V DC output with a very low current). All mounted on DIN rail to close elegantly in the switchboard.

I would like the contactor to be short-circuited by design and to open on a pulse from the satellite.

I have selected from allegro
GMC-65A contactor (I don't know how much will come from the riser, that's why 65A) for DIN rail
12v-230V relay on DIN rail

Please help choose the right devices price functionality quality and how to do it easiest and do I think right because I figured it out myself

I wanted to take one of the phases to the fuse (the one to Satel) and then return it to the contactor

Colleague @szelton has basically closed the topic, however, I would suggest adding a switch in parallel with the K2 contact, because in the event of a failure of the control panel, you will have no electricity when you enter the facility, and a small bistable switch (even on the facade of the cabinet, or if not then on a DIN rail) will not cost you much.

As for an NC contactor - I haven't personally come across one, and have no idea how about availability. But always the -K2 contact can be NC, and then the principle of operation will be as desired, and also the contactor can be cheaper

In addition - remember that equipment such as a fridge, aquarium pump, washing machine (as long as you are confident enough to leave it on in your absence) needs voltage all the time, as long as you live there all year round. That's why I'd put a contactor in front of the power supply of the already selected sections only.

And as far as the quality of the equipment is concerned - let's say you're not going to be switching pumps at your place for a number of kW, but on the other hand this contactor is going to work for a number of cycles. Wouldn't it be better to take something better than some "GMC"? (Remember, it's also about safety!).

Best use of output expander(s)

and disconnect individual circuits, there is also a version with inputs, the load capacity of the output is 16A so it is sufficient for most circuits.

Hello esteemed colleagues....

And how, did you manage to carry out the plan ?

I've just come across your post, gentlemen... and I'm thinking about how to make the power supply switch off when the fire alarm is triggered or for any other reason triggered from satel.... At the same time, I wanted to avoid using a large contactor, whose coil is always on, after all, also consumes some energy...with a 63A coil, it would take a lot of power...and I came up with an idea which may be a bit silly, but I think it's effective and should work... Well... from the control panel we go out to a small relay...and from there with some relay like R4 let's say or straight from the control panel if the coil consumption of its 12VDC version is not too high...we switch on some light or something ...between L and PE.... a differential should be triggered? is that right? We won't be able to switch it on remotely...but in an emergency?fire.... Enough...

Well I was just looking for such a device, but wasn't sure what it was called - hence my idea of an RCD.... I will use such a trigger to switch off the FR ?

Thank you. I'll have a look... I once checked the coil consumption of a 3-phase modular contactor out of curiosity.... And it seems to have come out to about 20W - so not so little. It's a shame that in normal operation... Hence the idea I quoted earlier, and in the event of a FPS trip...I guess it wouldn't hurt to switch off the power supply.
