Zero crossing for this application, being inductive load of the coil for the larger relay it's serving?
I've used the non-zero crossing G3MC-202PL-xx in similar situation before, considering the G3MC-202P-xx is for resistive load. In this application, because of a small load, I can make use of a smaller form factor, thus the one I chose. I suppose for larger application, but still low wattage either one zero or non-zero crossing would work okay though? I've used the non zero crossing G3MC-202PL-xx for switching the 24vac solenoid controlling a rainbird sprinkler valve.
