The round blue part is most likely a VDR, a Voltage Dependent Resistor, the diameter gives the power, the voltage is most likely 275 VAC

Good point. I think you're right. Haven't designed motor circuits, but that seems a common part at that place

Burning is your hobby?

Burning is your hobby?

No. There was just an accident and a lot of equipment burned down. I want to help fix the water pump and electric car charger.
So I ask for your help

I just looked but the only ones I have are these 250VAC 60J 2.5kA
The diameter is 11mm. I think they are too small for your application.

That is the problem, I know that in East Europe and more Eastwards our common companies do not operate in that area, there are the same sort of companies in that area of the world but i can't find them.
