Abstract (en)

1. A circuit breaker of the type comprising a fixed phase contact (14), a movable phase contact (15) which is urged by resilient opening means (21) in the direction of a tripped position in which it is spaced from said fixed phase contact (14), an actuating mechanism (16) which is intended on the one hand to cause said movable phase contact (15) to move into and be maintained in the closed position under the control of a closing and tripping hand lever (35) which is mounted movably between a closed position and a tripped position, and, on the other hand, to cause liberation of said movable phase contact (15), in response to the movable element (28) of a tripping member (17), at least one fixed neutral contact (19), a movable neutral contact (20) which is pilot-controlled in respect of closing and opening by said closing and tripping lever (35) and a disengageable locking member (60) which, under the control of the movable element (28) of the tripping member (17), is movable between an unlocking position in which it leaves free the movable neutral contact (20) and a locking position in which it temporarily holds same in a closed position, characterised in that said locking member (60) comes into action by way of the closing and tripping lever (35), said locking member (60) leaving free said closing and tripping lever (35) when said locking member is in the unlocking position and holding same temporarily in a closed position when said locking member is in a locking position.

Abstract (fr)

Dans ce disjoncteur sont prévus des contacts de neutre (19A, 19B et 20) dont le sectionnement est sous le contrôle de la manette d'enclenchement et de déclenchement (35) et un organe de verrouillage débrayable (60) qui, sous le contrôle du noyau (28) de l'organe de déclenchement magnétique (17), est mobile entre une position de déverrouillage pour laquelle il laisse libre le contact de neutre mobile (20) et une position de verrouillage, pour laquelle il maintient temporairement celui-ci en position enclenchée. Suivant l'invention, l'organe de verrouillage débrayable (60) intervient par l'intermédiaire de la manette d'enclenchement et de déclenchement (35). Application aux disjoncteurs.
