A triac is a triac, not an ssr. SSR's typically contain triac's and while I won't argue an SSR doesn't have to be zero crossing turn on, I haven't seen one that isn't, and I've used them for 25 years. The whole intent of SSR's were to cleanup the mess mechanical contacts caused. Anybody that has designed around sensitive measurement enviornments won't hot switch with mechanical contacts. They may isolate with mechanical contacts before or after a power on/off cycle, but not hot switch.
