Is the Eaton CHB245 breaker HACR rated?

Yes, the CHB245 is fully HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits.

    Was what I needed

    This breaker was exactly what I needed. I did not give it 5 starts because it was SUPER expensive for this frame size breaker.
