What does “NA” mean in circuit breaker ratings?
I am trying to find a exact replacement for a few breakers on a piece of equipment and I found two that seem like they would be the breakers I need, the only difference being “NA” in the part number and description. I’m not quite sure what it means and was hoping to get some help.
No “NA” notation: http://www.kempstoncontrols.co.uk/parts/ABB/S411K10.html
“NA”: http://www.kempstoncontrols.co.uk/parts/ABB/S411K10NA.html
Info from a distributor, just in case people were wondering:
The “NA” stands for “Switching the Neutral”.
The mini breakers for those part numbers are “K” type mini breakers, only the one with the “NA” in the part number has a neutral pole, while the other does not.
Mounting Hardware: N/A (plug in style breaker) ?
