Re: [TCML] Circuit breakers

Hmm, 

So I did some more digging and concluded that these are specialized circuit breakers. So getting a data sheet is going to be hard, I have an email into the company, but I am not holding my breath. 

I think you guys are right with the Ln its probably an In. It is still a little baffling that their appears to be 2 different values for voltage ratings. But these were on a 120V battery UPS so I am guessing that thats what they are rated for. 


Thanks for the assistance guys =),

IEC markings, vs, say, UL. 

U and L are probably used to avoid confusion with something else (even 
though V and I would be the more expected letters, at least in English) 

There's a variety of subscripts for each for things like maximum 
interrupting current, trip current, etc.
