The case rating of 3 VA was completey wrong, I measure the current with an ammeter and it measures 12A and 25A if the plunger was out of the solenoid.
I think I will need to use a 30A triac at least.
Thank you all.
Thank you all for your answers! but I still have some doubts. How do you calculate 4K impedance? The solenoid I want to drive is about 3"X3"X3" so it doesn't look that little and it is pretty powerful, 40ma seems very little current for this kind of solenoid.

I need to drive an AC solenoid that says 3VA in the case and measures 5ohm with a multimeter.
AC voltage is 110V and I want to use a triac, maybe a MAC15D. Is this enough? Should I put a snubber circuit in parallel to the triac?
Thank you for your help,
David.
