Patent

CA 2751698

A permanently installed manual trip mechanism is mounted internally to a circuit breaker with a user operated handle extending to the outside of the enclosure. The mechanism converts a relatively small operator input to larger spring charge. Upon triggering, the mechanism provides the required operating velocity of the circuit breaker during the opening stroke for load break operation.

L'invention porte sur un mécanisme de déclenchement manuel installé de façon permanente qui est monté à l'intérieur d'un disjoncteur avec une manette actionnée par l'utilisateur s'étendant à l'extérieur de l'enceinte. Le mécanisme convertit une relativement faible entrée de l'opérateur en une plus grande force de ressort. Lors du déclenchement, le mécanisme assure la vitesse de fonctionnement requise du disjoncteur au cours de l'ouverture pour une opération de coupure de charge.
