。[Scope of Claim for Utility Model Registration] A closing spring whose energy is stored by the rotational force of the motor via a deceleration mechanism, a closing spring holding mechanism that retains the stored force of the closing spring, and a closing spring whose energy is stored in response to a closing command. a closing trigger mechanism that releases force; a cutoff spring that stores energy by the releasing force of the closing spring;
An electric spring operating device for a circuit breaker, comprising a cutoff spring holding mechanism that holds the stored force of the cutoff spring, and a cutoff trigger mechanism that releases the stored force of the cutoff spring in response to a tripping command. a closing holding latch that is engaged with a connecting point of two links that transmit the stored force of a spring to the cutoff spring holding mechanism, and shares the stored force of the cutoff spring with the cutoff spring holding mechanism; A guide hole is provided for guiding a pin provided at the end of the link on the cutoff spring holding mechanism side of both links and fixing the pin with the cutoff spring holding mechanism during a closing operation. Electric spring actuator for circuit breakers.
