   It was due to a wiring fault, since cleared up. I bypassed the fuse and the   
   uint powers up and looks to be OK.

   If I was going to use this, for example, on my bench as a diagnostic tool   
   where I would have a hand on The Switch when it was being operated, I'd have   
   no qualms about cobbing together such a safety device. But for sale and   
   installation into a user's business--no way.   
      
   So it's kinda critical I get a replacement somehow. I'll contact those   
   manufacturers you mentioned and ask for samples. The equipment manufacturer   
   said that to repair this unit (the wiring fault is a common field install   
   error) would cost more than a new unit. Clearly marketing spin and or   
   outright lie, we now know. I'll ask about a replacement but not hopeful...   
      
   Thanks, SP for your insight.
