description The invention relates to the field of low-voltage electric appliances, in particular to an electric operating device of a circuit breaker, which is characterized in that when a switching push plate is positioned at a first position (second position), the electric operating device is switched to a manual working state (automatic working state), and a power supply circuit and/or a signal circuit are/is switched off (or the power supply circuit and/or the signal circuit are/is switched on); when the switching push plate is located at a second position and the locking mechanism is switched from the unlocking state to the locking state, the switching push plate is locked and the power supply circuit and/or the signal circuit are/is driven to be disconnected at the same time; when the switching push plate is located at the first position and the locking mechanism is switched from the unlocking state to the locking state, the locking mechanism drives the switching push plate to move from the first position to the se
