Re: [TCML] Circuit breakers

   Took a Real Casual/quick look:
     Ue shows up as rated voltage
     Ln as Rated current.

   Now one may ask: waitaminnit, there seem to be TWO
   different values for voltage and current?

   I'd expect this to be two different 'regulatory authorities'
   defining things Slightly Differently.  Could be wrong.

   The suggestion to hunt up the manufacturer's website is
   well made, in my opinion.  (I simply googled
   'Ue Ln Circuit Breaker'.)  IF those are industry
   standard abbreviations, likely show up elsewhere...
