Can an 800A P frame circuit breaker be installed as a branch breaker in an existing HCW interior?

Issue:
Legacy HCW I-Line panel interior accept an 800A P frame Powerpact circuit breaker?

Product Line:
I-Line panelboards

Environment:
Products sold in North America

Resolution:
The P frame circuit breaker cannot be installed in an existing HCW main lug interior for a couple of reasons.

The deadfront of the HCW interior is not designed to accept dimensions of the newer P frame circuit breaker.  Also, there is no labeling to support the use of a P frame circuit breaker.
