I just checked my parts box SSRs and found that I have 2 Magnecraft (10A), 29 Crydom (50A, 40A, 25A, 10A) and just one cheap Chinese Fostek 25A SSR (via AliExpress). I've used it for only 1-2A projects. I watched a DIY YouTube review that revealed it has an underrated TRIAC and will only work up to 16A. What a scam! And now thanks to you I will be doubly careful with it. But really, when it comes to that much power and risk of electrocution/damage/burning your house down, stick to the reliable Crydom. I just looked up the highest rated Crydom model.. 125A. Wow.
