Do you recall the brand label? And more importantly, what was the load 
device?

I had, when I was the CE at WDTV, a studio lighting control with 36 3k 
watt channels, full of crydom 30 amp SSR's.  The studio, since I've 
retired has better cameras and much of its lighting in now led based 
except the overheads which are now various types of HO CCFL's. But in my 
18 years there I had probably 6 or 7 cd4000 logic chip failures in the 
control panel, and zero SSR failures.  Patch cord burnups, several, but 
no SSR failures.  I came to the conclusion that crydom makes very good 
stuff.  Other brands not so lucky maybe. IDK, this one blown shorted is 
the first failure I have had of any of this "style" of SSR's. When I 
have removed it and built the soft start in its place and have it 
working I may grind this one open and report what I find, if by then my 
back still feels like messing with it. Since I'll be 3 steps up a ladder 
doing all that, doubtfull.

Thanks Andy & Todd.

Cheers, Gene Heskett
