Thanks guys.
There are 2 2-pole breakers total, both the same, only the upper one is bad, lower is working. Luckily we still have the heatpump and half the aux heating working. And we don't live there yet so I keep it at 65.
It's a Trane unit with lots of honeywell things added on(elec air cleaner,humidifier,perfect climate).

I couldn't find a number for the heat pack.
When I had the home inspected the inspector pointed out the breaker and leak. He had to toggle the breaker a couple times to get it to work.
I've been keeping a eye on it since and noticed it tripped Saturday only now it acts like a dead breaker, won't go open or closed.
If there was for sure a direct replacement breaker for the QCD2060 and it was readily available I'd use it.
Otherwise I'm leary to use other than OEM parts on something like this.
19 days or less according to Grainger until they get me 2 of them. Fingers crossed. Looks like they will be my best bet at $71 each.

Not sure if it's compatible but might be worth asking.
Not sure on the dimensions but the voltage rating is not the same as what I'm replacing.
