Abstract
A latching device for a circuit breaker includes a manual operating toggle moveably arranged between an OFF-position and an operation-readiness position, a moveable contact and a fixed contact, wherein the moveable contact is configured to open and close a main circuit of the circuit breaker. An energy storage mechanism is configured to store an actuating force of the toggle by the toggle being moved from the OFF-position to the operation-readiness position and to exert the stored force to the moveable contact to close the main circuit of the circuit breaker. A removable retention lever is configured to prevent movement of the moveable contact into a closing position upon the energy storage mechanism exerting the stored force to the moveable contact. A holding mechanism is configured to hold the toggle in the operation-readiness position.
