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.
