MTZ, NS Compact, rated peak withstand current Ipk

[KrunoslavSever]

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.

Best regards,
