An external operation handle device for a circuit breaker includes a rotary handle equipped with a handle lock lever, a drive mechanism linking the rotary handle and the locker handle of the circuit breaker, and a door lock lever for interlocking between the rotary handle and a door of the board. Said agent is produced by mixing two constituents and, and is characterised in that the constituent contains at least one quinonimine derivative of formula, and the constituent contains at least one compound from the group consisting of aromatic amines and phenols. A second ramping voltage is generated in response to the first ramping voltage. A means to filter is disposed in the path of the separated ions and it allows ions to pass through more easily than uncharged molecules.
