It could be that the breaker is undersized for your heat pump. Check the maximum amps on the system to make sure. Another cause could be that there's actually something wrong and it's drawing too many amps (this can happen as motors age). An electrician has the tools to check this, and should only charge about $50 to check.

A breaker will only trip when there is a circuit overload somewhere in the line. For some reason the heat pump is pulling to much current. Check for short circuits anywhere you can see, and if you don't see any, I would call an HVAC repair person.

The heat pump has a tungsten or other good quality heat producing material. At times when over voltage creeps in the tungsten filament gets over heated leading to its snapping , the replacment of which is a costly affiar. A limit switch provided in the pumps does the job of tripping.

A heat pump is a high current device. You might have another load on the same circuit. Remove the extra device. If none, heat pump or breaker is defective.

There are two reason that this might happen to your heat pump. One, your heat pump might have a short in it somewhere. The other reason might be that your using too many amps on that circuit. Add up all the electrical devices amperage on that line and see if you are over your breakers limit.
