Abstract
An auxiliary apparatus is coupled to an electric circuit breaker. In the open position, the breaker interrupts the circulation of a current in an electrical connection, which includes at least one electrical conductor and a mechanical output member movable between an operating position and a stop position associated with the interruption of the circulation of the current in the connection after opening of the breaker. The auxiliary apparatus includes at least one current sensor to measure the current circulating in a respective conductor, and a mechanical coupler to couple with the mechanical output member. The mechanical coupler also detects the opening of the breaker. The auxiliary apparatus also includes a device for determining a cause of the detected opening, based on the intensity measured by the current sensor.
