Abstract: PROBLEM TO BE SOLVED: To easily assemble a power transmission mechanism is a hybrid electric power breaker. SOLUTION: The hybrid electric power breaker comprises at least two arc- extinguishing chambers that are connected in series and these arc-extinguishing chambers can be operated by a common drive device through a power transmission mechanism 29 that is arranged connected in front of the arc-extinguishing chamber. The power transmission mechanism 29 is formed capable of insertion connection by at least two power transmission components and the first power transmission component is connected fixed to at least one first arc-extinguishing chamber and the second power transmission component is connected fixed to at least one second arc-extinguishing chamber, and the power transmission mechanism comprises a means that can mutually harmonize technically and appropriately the movement of at least two arc-extinguishing chambers and optimize order in time and switching speed of the movement of the arc- extinguishing chambers.
