  • Patent number: 9484167
    Abstract: Disclosed is a coupling device for a circuit breaker. A third coupler formed as a curved surface is provided between a first coupler coupled to an outer handle assembly, and a second coupler coupled to an inner handle. Under such configuration, even if the inner handle and the outer handle assembly are not concentric with each other, the third coupler may transmit a rotational force applied to the first coupler to the second coupler in a direction perpendicular to a shaft direction of the second coupler, in a state where the third coupler is inclined from an upper surface of the circuit breaker body. As a result, a user's force to rotate the outer handle can be transmitted to the inner handle. This can prevent a malfunction of the circuit breaker, and thus can enhance reliability of the circuit breaker.
