just a guess
just looking at it it looks like they are using the contactors as a transfer switch,.
IE, one contactor is for commercial power and the other is for gen power.
when commercial power is lost, that contactor opens and when the gen comes up, it closes the gen contactor. just a guess based on it looks like one of each pair is energized.

just search the part number for the contactor to get a price.

the 2 cut red wires does not look very safe.

Yes, that's the way I was thinking this setup works... Do you think these contacts are before the meters? I would assume this. I think the cut red wires are for the contactors which would feed our villa. Your right, the red wires do not look very safe, but that's par for the country, lots of amputees here. I should also mention, currently we do not have backup/generator power when the commercial power is out...
