Claims

[Scope of utility model registration request]

A main contactor device consisting of a fixed contactor and a movable contactor assembly that can be moved into and out of contact with the fixed contactor, a side plate arranged in parallel on the front side parallel to the axis of the main contactor device, and one end of which is attached to the side plate. a toggle mechanism that is pivotally supported and whose other end is connected to the movable contact assembly and moves the movable contact assembly to a closed position when standing up and to an open position when collapsed; and a toggle mechanism that is engaged with the toggle mechanism and is in a collapsed state. a drive mechanism having an operating shaft fitted with a cam that stores the released closing spring set and is pivoted to the side plate; and a drive mechanism that is connected to the operating shaft via a one-way clutch and has an opening at the front end. an operating lever having a wide groove; an auxiliary lever that is coupled to the operating lever so as to be rotatable in one direction and closes the groove; a lever that is stretched between the operating lever and the auxiliary lever and biases each other in the direction of closing the groove; and an electric operating device that is rotatably fitted between the groove of the operating lever and closed by the auxiliary lever and rotated by an eccentric pin coupled to a speed reduction mechanism of the drive motor. Electrically operated circuit breaker.
