Abstract: An electrical apparatus for breaking an electric current includes an electrical arc extinguishing chamber, for extinguishing an electrical arc formed on the separation of electric contacts, provided with an extinguishing gas exhaust orifice and an extinguishing gas filtration system, placed at the output of the exhaust orifice and including a filter and a gas diffusor. The gas diffuser includes, superposed between them, a central layer and two outer layers arranged on either side of the central layer. The central layer is provided with first through holes. Each outer layer is provided with second through holes. The first holes are misaligned relative to the second holes so that each of the second holes emerges on a solid portion of the central layer without any first hole.

Abstract: A device for short-circuiting an electrical installation that includes at least two electrical conductors, the device including at least two connection terminals, each configured to be connected to a respective electrical conductor, an electromechanical unit configured to establish a short-circuit between the connection terminals, and at least one resistive element configured to connect one of the connection terminals to the corresponding electrical conductor. Each resistive element includes a first connection end connected to the corresponding connection terminal and a second connection end configured to be connected to the corresponding electrical conductor. The resistive element has an impedance, and variation in a value of the impedance is less than 1 mΩ for a temperature of the resistive element of 0° C. to 200° C.

Abstract: A multipolar electrical protection device has a disconnecting block with separable contacts containing at least one movable contact finger, a switching mechanism able to move the contact fingers, and an electronic tripping system that drives the mechanism. The protection device has a pyrotechnic actuation system including: a pyrotechnic actuator; firing pins positioned facing the contact fingers and each able to be moved to a pressed position in which it pushes a contact finger; a motion transmission system for transforming the movement of a mobile part of the pyrotechnic actuator to the deployed position thereof into a simultaneous movement of all of the firing pins to the pressed position. The tripping system is able to activate a pyrotechnic actuator when it detects an electrical fault.
