Abstract:
A blocking apparatus for blocking a contact structure from closing in a circuit breaker (10) is provided. The apparatus includes a link (182) extending from the circuit breaker and connected to amovable contact (46) arm. The contact structure, being operated by an operating mechanism (28), remains in a separated position even when the operating mechanism (28) is in the "ON" position due to the connection with the link (182) of the blocking apparatus. A realease assembly (184) releases the link (182) when it is desired to close the movable contact (46) arm.
