摘要： The invention relates to a cut-off device comprising: a conductive element and a movable piston, the piston being able to move between a first position in which the current passes in the conductive element and a second position in which the current is cut off, the piston being configured to break the conductive element when moving from its first position to its second position, the piston being positioned in a receiving cavity of a receiving element when said piston is in its second position,



characterized in that the receiving element further comprises at least one additional cavity separate from the receiving cavity and linked to said receiving cavity by at least one channel, said at least one channel being open when the conductive element is broken by the piston.

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.
