RE: [ATM] Making glass blanks

Many of the solid state relays have built in zero-crossing and are optically isolated (protects the PC).  Just a quick look in the Digikey catalog: something like a Sharp S216S02  (16A, $6.23) or a module like the Omron GANA-225B-DC25-5 (25a, $18.80).  IMHO, the module with screw terminals will be easier to use.

There are even 3 phase systems up to 530V and 50A ($142.38) if needed :-).

Not related to any company above.  Check that the components meet your design specifications.

Please do not forget that switching large amount of power
is producing unwanted and even prohibited pollution
of the power net and therefore must be done at the moment when
AC sinusoidal waveform of the mains is crossing zero volts.
