To add to that, a 1:1 control transformer of a very small size
can be wired as a buck boost to operate that coil.
As I mentioned previously, the solenoid requires a 5.2 amp pulse
to properly actuate the contactor mechanism.
With a 240/240 control transformer wired up in boost mode that
would need at 1000 VA transformer as a bare minimum.

Then it must be pushing a large load a long distance.
at that current, you looks like you have ~ 100 ohm coil.
which means the wire in the coil is rather a large gauge since
this is DC going to it.
I would start around 20awg and see what the DCR 1M is on the
chart. Then see if that will physically fit on the form.
