Hi Juul and

to the forum.
The website you linked to shows different versions of the contactor are available for the following voltage options:
12V
24V
36V
48V
60V
72V
And the contacts are rated for 6-80V, so I'm not sure what the "Coil voltage of contact circuit (V) 6V-220V" actually relates to.

The coil voltage should be marked on the body of the contactor, similar to these:

The above contactor has a coil rated for 12VDC but the contacts are rated for 400A @ 80VDC.
The contactors shown below just have the coil voltage marked, but the contacts are presumably capable of switching 400A @ the marked voltage:

Hopefully your contactor will be clearly marked too.
