Eaton just announced some safety switches with shunt trip that may work
for you- Google: Eaton TD008003EN to get the datasheet.

Greetings Esteemed Wrenches,
We are building a 35.75kW project with (6) Power One 6000's. The
service is a 240 delta. The utility is requiring (late in the game)
that if one leg of the service is lost, all inverters must shut down.
Of course, we have two inverters that do not shut down in that
circumstance because they are only tied into the other two phases. SMA
has a good (cheap) option to deal with this, SMA Power Balancers. With
other inverters this can be accomplished by installing an ATS with an
integrated controller by programming in the unacceptable phase
imbalance (expensive). Does anyone have experience with this
requirement and/or have a good (cheaper) solution?
Thank you in advance!
