To rozwiązanie byłoby super tylko że z tego co widzę w dokumentacji wersja ta z triakiem jest dobrym rozwiązaniem dla obciążeń rezystancjach. (Patrz załączona dokumentacja). Jest w niej napisane że występuje dwóch trybach np. GT1044ZD3 lub GTH1044ZD3 Gdzie literka H oznacza posiadanie wyjścia SCR a jej brak - wersje z właśnie z wyjściem "triakowym". Nie mogę znaleść również aby posiadał on tak jak Ryszard wspomniał, dwójknik LC. Czy w takiej sytuacji wciąż SSR ten byłby dobrym rozwiązaniem ?

Solid state relays
GT 10 to 40 Amps AC SSR
The series GT three phase Solid State Relays is used three phase loads. Triac Output. The triac version of the
zero switching relay is an inexpensive solution for resistive loads. The zero switching relay switches on when
the AC sine voltage just crosses zero, and switches off when the current crosses zero.
