Abstract: An aircraft with electric or hybrid propulsion which includes an electrical installation including at least a first electrical network and at least a second electrical network operating at a voltage higher than that of the first electrical network. This second electrical network includes at least an electrical-energy distribution system, at least a reversible electric motor for aircraft propulsion directly or indirectly connected to the electrical-energy distribution system, at least a reversible electrical system directly or indirectly connected to the electrical-energy distribution system, and a safety unit positioned as close as possible to each electric motor and to each reversible electrical system.

Abstract: A switching device including at least one main breaker, an actuator configured to cause a change of state of the main breaker, from a first to a second state, counter to a spring generated force, the actuator being powered by a control signal equal to a first level to cause the change of state of the main breaker then to a second, lower level, to hold the main breaker in the second state. The switching device comprises a current sensor configured to control the control signal to increase it to a third level higher than the second level if the current flowing in the main breaker is higher than or equal to a given operating threshold, to avoid a spurious change of state of the main breaker. The switching device comprises a re-armable protection system for controlling the time for which the control signal is held at the third level.

Abstract: A switching device includes at least one main contactor, a control power supply and an actuator configured to cause the main contactor to change from an open to a closed state against a force generated by the spring. The contactor has a blade and at least one terminal, the blade being configured to assume a position in contact with the terminal and a position not in contact with the terminal. The switching device includes a detection system configured to determine the contact or non-contact blade position of the main contactor, to generate at least one second signal as a function of the determined blade position of the main contactor and to transmit the second signal to the control power supply. The control power supply is configured to generate a control signal configured to keep the main contactor in the closed state upon reception of the second signal.

Abstract: An electrical circuit breaker assembly, and a method for its operation, including a conductive element of an electrical circuit and a cut-off device configured to be activated by a pyrotechnic element and that is configured to sever the conductive element in a cut-off zone delimited by a downstream point. The electrical circuit breaker assembly further includes a contactor element configured to be activated by a pyrotechnic element, the contactor element being configured to connect the downstream point of the cut-off zone to an earth conductor of the electrical circuit prior to a severing of the conductive element or simultaneously with the severing of the conductive element.
