Compact NS current limiting curves

[KrunoslavSever]

Hello,

I've received a question from a customer about current limiting curves for compact NS1250N breaker. In our catalogue we have a graph with representative curve. The question is how to read the graph for specific value of 24 kA current? Do we have a online tool maybe? 

Best regards,

K

Also, 

is it possible to see those curves in Ecodial? Currently, I can see only I-t curve in ecodial.

Thank you,

K

For the graph, you just find where the 24 kA mark hits the curve and then check the values on the axes. As for an online tool, try looking on the manufacturer's website or give their support a shout. They usually have something that can help.

hello @KrunoslavSever 

Sorry I saw the question just today

As I know no tools exist to read them

Don't hesitate to ask this type of question to CCC

For 24kA we can read around 13.5kA. You must know this value are determined by simulation and calculation to help the panel board design. Nevertheless, at end panel builder need to plan a Icc test to validate the product integration.
