Hello everyone!
The link avove points to a contactor switch datasheet. That contactor is used in my house instalation. The question came accross is: Looking at the datasheet table, there is control circuit section. What this data mean?: Operating range factor control supply voltage rated value / ofthe magnet coil 0.8 … 1.1.

So again what means that range? If someone can describe that parameter little bit more, I would much appreciate that?
Thank you in advance!

control voltage range 0.8 ... 1.1 says the contactor will be safely engaged with a coil voltage > 184 VAC. The coil shouldn't be exposed to a voltage above 253 VAC to prevent overheating.

Thank you for your prompt reply!
I tought so too. What confused me is, that I anticipated real numbers (what you showed me) rather than relative range (0.8 - 1.1)*rated_voltage. Anyway, thank you again.
