Zusammenfassung:A blocking apparatus for blocking a contact structure from closing in a circuit breaker is provided. The apparatus includes a link extending from the circuit breaker and connected to a movable contact arm. The contact structure, being operated by an operating mechanism, remains in a separated position even when the operating mechanism is in the "ON" position due to the connection with the link of the blocking apparatus. A release assembly releases the link when it is desired to close the movable contact arm.
