Solid State Relay - SSR-40 DA

FYI, it says 40A but this is AC.... you're not going to be running 120v mains at 40A anyway.... at most 15A and that would be 1600 watts.... 12amps is about what i would expect as it's quite common, like those smart plugs would only be 10-12 amps too.... that will do a 1400w AC heated bed. a 1400w silicone bed would probably cook a steak.... a 700w will easily get to 200c.... so as long as it don't catch fire.... i have a few china ones and they're ok... it's just people over rating them on DC SSR's not understanding much of anything.....

After watching bigclivedotcom's video on a fotek SSR, I took a look at mine. I bought this a while back from spool3d, and inside is a (maybe genuine) ST micro BTA12 integrated snubber+triac rated for 12A. This relay will never get to 40A continuous current. If you attempt it, it may blow up in spectacular fashion. I do see something that might be a ptc fuse that may protect the triac from blowing up, but I haven't verified it isn't just a plain capacitor, or if it is a ptc or similar device, what its rated for. The ssr is epoxied to some degree and trying to lift up the component may destroy it.
