Hello,
I have a question from a client regarding rated peak withstand current Ipk. Is there somewhere info about this currents for MTZ and NS type of breakers?
In catalogue I can find Icu,Ics, Icw but Ipk is not declared?
Any help is appriciated.
Meanwhile, I found for compact NS 1600 info Icw=19,2 kA. Why is for compact type of breaker Icw current declared? Isn't that current specific for air circuit breakers?
Best regards,
K

Thank you for your info.
Can you please share info why is Icw 19,2 kA only provided for 690VAC but not for 400VAC also? Or why is provided for A type Circuit breaker at all?
By A type, I mean - Selectivity category A.
