I would like to make an automatic switch that cuts AC off after the voltage
becomes low and remains off until manually reset.  Some surge suppressors in
the $100 range have this dropout feature.  I can do this with a relay, but
I don't know how reliable that is and at what voltage it would drop out.  Is
there a more reliable (solid state?) way of doing this?

Please email or post, as probably many other people would also like to know.
Thanks.
