The triac being underrated does not give confidence in these Chinese clones. It is not even clear if it is zero crossing, but as the driver chip seems to have six pins it is likely to be an MOC3063 which is zero crossing. Some of these Chinese SSRs that people have bought are not zero crossing. One in particular, that was very popular among home brewers had its internal circuit diagram published on the ebay sellers page and that certainly was not zero crossing.
It is probably safer, for those with the skills, to build their own. One snubberless triac of a rating of choice, one MOC3063 and three resistors and the job is done. Won't match Chinese prices, but is still quite inexpensive and at least you know what you have got. The most expensive bit is the heatsink, but you can buy that from China with relative security.
