摘要： Electrical device comprising a body defining a closed inner space, a first electrode, a second electrode and a third electrode, a free end of each electrode opening inside the inner space, the free ends of each electrode being arranged, inside the inner space, apart from one another and opposite the other electrodes, the electrical device being configured to prohibit the current from flowing between the first electrode and the third electrode when the electric current or the electric voltage between the first electrode and the second electrode remains below a predefined threshold value; when the electric current or the electric voltage exceeds the threshold value, allow the current to flow between the first electrode and the third electrode.

摘要： An electric circuit breaker comprising a switch, an arc extinguishing chamber and a fuse configured to be electrically connected between first and second terminals after the switch has tripped, further comprises a connection device comprising a gate configured to be broken after the switch has tripped only when at least one of the temperature, the pressure inside the arc extinguishing chamber or the intensity of an electrical arc present in the arc extinguishing chamber passes a predefined threshold, the connection device being configured to connect an electrode of the fuse to one of the terminals of the electrical conductor only once the gate is broken.

摘要： A protection device for an electrical circuit comprising at least one circuit breaker comprising a control zone, suitable for receiving a tripping signal (S), and a power zone for the passage of electric current. The device also comprises a control circuit configured to produce and transmit the tripping signal to the control zone. The device further comprises a fuse connected in series between the first conductor and the circuit breaker and capable of supplying a supply voltage (V) to the control circuit, the control circuit being connected between the fuse and the control zone.
