We do not have a stall current for these motors, you can carry out your own low voltage test to determine the figure but you could also assume a figure of 6-8 times the motors FLC. I would estimate 5A at 3V. Providing thermal cutout is difficult. Motors can pull large currents simply by accelerating hard or by quickly reversing. If you have a cut out selected that it does not open during heavy loads, then it is also unlikely to open quick enough under stall conditions. Most motors will burn out their windings under stall conditions more quickly than a thermal device can operate at. You may be lucky but do check the thermal devices time / current relationship first.
