Question:

The circuit breaker of the Ultra-Fab Electric A-Frame Jack # UF38-944017 is designed to prevent the motor from drawing too much amperage and damaging itself. If you were to lower the jack all the way and then keep holding the button you eventually would trip the breaker, but more importantly you would potentially damage the threads of the internal screw of the jack which would permanently break it.

I would not advise you rely on the breaker to or the threads bottoming out to let you know when the jack is as low as possible.

I think the best value for an A-frame tongue jack is the Stromberg Carlson # SC63VR which is rated for 4500 pounds of tongue weight. This is 1000 pounds more than other models, and even though you may not need this much capacity, you will find that the jack motor runs quick and effortlessly. This will add years to its life. This jack also has a unique clutch that prevents damage from overextending or retracting the jack foot - the most common reason for jack failure. I also like that is has a generous 23" lift, including a time-saving drop-foot. It includes LED lights for operating the hitch in the dark, and a built-in bullseye leveling bubble.
