How to be sure a SSR has not been damaged when its circuit breaker has tripped?
Protecting Thrysisters against fault currents is no mean feat because prospective fault currents can be thousands of amps .We were concerned about this on an industrial light dimmer project 22 years ago .Oversizing the thrysisters and adding some inductive reactance will sort this out .If you dont add the reactance you may find the SSR that can do the peak fault unobtainium like we did then .SCR type technology has not got much better over recent decades.Your inducter will be large and it must not saturate under faults .Anything with a closed field is a nono.I prototyped an air cored coil wound on a transformer bobbin .When you now look at total cost and size its now time to consider an IGBT based system . If you turn off the IGBT in less than generally 10 microseconds it wont die .
