An electrical power supply disconnector for establishing or severing the connection between current conductors and a power supply circuit. The electrical power supply disconnector includes a housing including a central passage, the walls of which bear contact strips that are located facing one another along a contact axis, and a slider sliding through the central passage in the direction of a centre axis, and bearing at least a first electrically conductive bar, oriented along the contact axis, for electrically connecting at least one first low contact strip and one high contact strip when the slider is in a first position. A protection module including such a power supply disconnector.

A current measurement device including current sensors positioned around current conductors in order to form a passage for the current conductors along an axis oriented in a first direction and a differential current sensor positioned around the set of current conductors in order to form a common passage for the current conductors along an axis oriented in a second direction. The current sensors and the differential current sensor are located in spaces that are separated by an interface plane. A method for manufacturing such a current measurement device, to a protection module and a differential circuit breaker including such a device.

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.
