Great video. At time 2.18 you said the plunger pushes against the breaker (the plastic paddle I will call it). What I would really like to know is how the 'paddle' when forced upwards by the voltage being removed from the undervltage solenoid and the plunger raising upwards onto the 'paddle'... What other mechanism is involved to force the spring to open the breaker. Is there a release pin or something attached to the 'paddle'
