Answer by Jim
When the Motor starter is energized all the current of each leg passes through a resistance coil around a spring loaded peg. The peg is held in place by solder inside a tube around it. If the motor draws too much current the resistance coil heats up melting the solder and releasing the pin which is connected to a switch that disconnects the motor from the power. The reset button, when pushed, resets the peg against spring pressure and allows the motor to start again.
