Probably in the maintenance kit...

Thank you Sir. But I had already gone through those manual and the link. But I couldn't find the dimensions of sealing ring. Need exact size of sealing ring.

Thank you.

Well this might well be considered proprietary information as to not only the dimensions but the composition and manufacturing details and as such would be protected under intellectual property laws...

It is a common misconception that intellectual property laws permit the inventor to maintain secrecy about a given process or construction. The opposite is the case. If Siemens holds a patent on the dimensions/composition/manufacturing details of the referenced sealing ring, then said sealing ring must be described in sufficient detail in the patent document to enable anyone to reproduce it. Intellectual property law would protect Siemens' right of exclusive ownership, and its right to licence or sell whatever process or construction is disclosed and claimed in the patent document, but provides no right of secrecy.

An inventor who wishes to keep an invention secret will not apply for patent protection. This is the category of trade secrets - the formula for Coca-Cola, for example. The formula for Drambuie, my Christmas-treat liqueur, is also a trade secret. It is entirely possible that the composition/manufacturing details of the referenced sealing ring are kept as a trade secret by Siemens.

There are many types of intellectual property protected by various laws, including non-disclosure agreements... ..I am guessing that Siemens insists that you use their kits and parts to repair their equipment for various reasons....but this is just speculation..

Specialized information like this can really only come from Siemens, you will need to contact them directly for the information.

Given the application they may not give it however as if you have a sealing ring failure they will likely require the circuit breaker to be sent back to them for service or replaced entirely.

It is very likely you may NOT be able to service the circuit breaker yourself, do not try until you contact Siemens for guidence. Failure to follow proper procedures could result in an arc flash explosion and injury or death.

Is there some reason that this matter cannot be sorted out over the phone to <...Siemens...>? What was the outcome of the calls made so far?
