Double check your breaker -- physically, how big is it?

And what do you mean by rated? Is it rated to trip at 10,000 A (10 kA)? or is this the fault current it will operate without coming apart (the trip setting being actually much smaller).... read the label vary carefully...

easy way to answer your question

if the breaker is the size of a cigarette pack then it's 10k fault current

if it's the size of a small car then it's 10k trip current

Panelman: thanks, that's why I asked the question... I had assumed it was the smaller, but didn't understand exactly kbravo's intent -- thought I'd ask...
 
Hey Guys Thanks for the Help...The Braker is Defiently not as big as a car...So it must be Fault Current..

How can I determine the Trip Current Amperage.

The Breaker is a Moeller FAZ-3-C32 10KA
 
Imok2, it should be 5..10 times the current rating (C-characteristic, not D-characteristic. See also page 10 for the trip curve (upper left picture).
Good link imok2.
