There is certainly much to be liked about the SSR's but if I was going to use them on an a/c system I'd probably use a pair in series w/ some form of a real time fault test across each.. I've had them fail in the past and they can fail open or closed.. on some systems that would/could spell disaster..

 

Fwiw

They are about the same cost, and handle the same load but are there other reasons why I haven't  seen the SSRs used. I am using the Vertical Power VP-X which makes extensive use of Solid State Relays so I wonder if their time has come and I should design the power distribution with SSRs?
