type CP breaker for A/C unit

[AHI in AR]

I found a newer-looking breaker on a 1994 condensing unit today labeled as type CP, not HACR. Is this kosher? Tag on unit didn't specify type HACR, and size was OK.

I don't know what the CP is all about, but the HACR label was dropped several years ago. As breaker technology and quality improved, pretty much all breakers qualified as HACR, so UL dropped the designation.
