Yes, my password is: Dear Amey, If I understood your question well, the difference comes from ratio of nominal Icn and ultimate Icu breaking capacities ratio to service breaking capacity Ics. You should contact the technical support of Schneider Electric in your country. Still a lot of DBs with only s installed.

Really very useful information. I do not have example of the breaker to comment this point.

I would really appreciate any help provided. Difference is in the breaking technology and size.
