Default Contactors, Would any of these work?

Here are a couple of links for contactors I can get locally:
http://addison-electronique.com/cata...s-120vac-60hz/
or
http://addison-electronique.com/cata...-3pst-3-x-n-o/
or
http://addison-electronique.com/cata...-3pst-3-x-n-o/
Would any of those work in a 30 amp e-brewery?

It depends on what you are trying to do.

The first 2 in your list are for 120vac operation i.e. the coil for engaging and disengaging the relay. The first one can handle switching 220v. The second one can handle switching 120v.

The third relay is for 220v operation of the relay and can handle switching 220v.

I just understood why the 120v coil after I posted that diagram. So the second one would probably work but now I am curious about the first one (250 VAC / 28 VDC)
