Question about Heating & Cooling
Something is either shorted or grounded. Check your compressor and fan motor(s) with an ohm meter to ground and across the terminals. If you get continuity to ground, the part is grounded. If you have no measurable resistance across the terminals, the part is shorted out.

It works just like a normal circuit breaker with one additional function. A shunt-trip breaker also has a built-in magnetic coil that can be energized externally to trip the breaker.
So what is wired to the shunt that is not letting the breaker reset?
