Is there single phase contactor for AC3 application?

There is not a  single phase contactor for AC3 application. However you can use LC1D contactor.
When using a TeSys overload relay which has single phase sensitivity, the overload must be wired to electrically defeat this feature.  If any of the bimetals are left unpowered the overload will eventually trip.
The power wiring shown below is for 240VAC (single phase)
