If there's something else on when you get the compressor started up, then it will trip. Hook a meter up and you'll see the amperage spike up way past the 12 amps on start-up. All motors do this. It's not unusual to see a spike of 22 for a fraction of a second and this may be the reason it keeps tripping. If it doesn't happen on start-up, it'll happen when the compressor cycles each time when deamnding air for the tank. Sooner or later, it's gonna get ya on one of them. Also... the harder that motor works and pressure builds, the more amperage you draw. If the motor is on it's way out it will trip the breaker as well. Check your pressure sensors and the like to see if they are clogged or need to be replaced. You'd be surprised how many problems a non-functioning piece can effect something somewhere else.
