Patent

CA 2547717

Certain exemplary embodiments can comprise an apparatus comprising: a current transformer adapted to provide a signal correlated to an amperage of an alternating current of a first phase of an electric circuit, the alternating current flowing through a circuit breaker; and a microprocessor adapted to receive the signal from said current transformer, and to cause the circuit breaker to trip responsive to the signal exceeding a predetermined threshold.

Certains modes de réalisation exemplaires de la présente invention concernent un appareil comprenant : un transformateur de courant conçu pour fournir un signal corrélé avec une intensité d'un courant alternatif d'une première phase d'un circuit électrique, le courant alternatif passant dans un disjoncteur ; et un microprocesseur conçu pour recevoir le signal provenant dudit transformateur de courant, et pour déclencher le disjoncteur en réponse à un signal supérieur à un seuil prédéterminé.
