3f + dry-running motor protection + switch + contactor. Work?

I warmly welcome.
Well, for some time I am preparing to set up a summer house hydrophore tank together with a pump and a three-phase motor with a capacity of 3kW 1460obr with which the pump works all my life. As the house runs through the forest, it often rains, winds etc. are missing a phase. This does not happen often but already 2 engines rewound because of this, so I do not want to rewind 3 especially that the one in question was never rewound (old Polish tamel).

Will such solution work properly ??
At the moment the hydroquard is drawn on the diagram but there was never enough water in the well so at the moment I can not use it (skip).
In the diagram, black is the power supply for the L1, L2, L3 motor and ground / ground) and red for the contact of the phase loss sensor, contactor coil, pressure switch and in the future (or not at all) dry-running protection, the above connected in series.

First of all, power the control system behind protection, not as before, from now.

Familiarize yourself with this:

Thank you gentlemen for the answers.
Still such a question, will a contactor like the one in the picture 20 amp be suitable (not failed) for a 3kw motor ??
Motor protection is enough C10 (10 amps?) Or do you need to give at least C16?
Or maybe a contactor to give a separate circuit so that it does not turn on each time the pressure switch is turned on, but it is turned on all the time (as long as there are 3 phases)? I think it would extend the life of the contactor.

There is a clever and relatively inexpensive DPC-10A controller on the market, operating on the basis of a pressure sensor. First of all, it serves as a pressure switch with the possibility of a very precise on / off pressure setting and with an additional time delay (prevents hydraulic shocks in the system and switching the pump on too often in the absence of a pressure tank). At the same time, you can set the operating pressure indication on it, below which the system operation indicates the occurrence of dry running + you program the time for which this situation must occur for the controller to turn off the pump.

As standard, this controller is offered with a socket and plug for easy connection of a single-phase pump, but versions with bare wiring and the possibility of connecting the device via a contactor and controlling a 3-phase pump are also available, assuming that the contact load does not exceed 12A. Such versions are often used in industrial equipment systems. It's best to ask the manufacturer's representative.
