Let us wish you a happy birthday! Assuming construction is similar to what we found, it appears that as long as they are derated down to be within their 12A limit and have good heat sinking at higher power levels over maybe 6- 7A, they should probably perform OK.

They also appeared to be counterfeit and came from the same supplier, but I could not find any performance issue with them during testing and they were built with 80NF70 MOSFETs which should be up to the job to meet the full spec. I know about inrush surge current when a compressor starts but it should be well within the limits of the SSR. They are still very popular way of switching power electronics.

Elec guy 12 November, at 9: AmazonGlobal Ship Orders Internationally. RC snubber circuit reduces those spikes to ensure safe and reliable operation of SSR. A few weeks OK – then a terrible smell. I have also tried just putting it on the 5V pin just to lock it up, but can try it completely separated with a 5V walwart or the like.
