Abstract (en)

[origin: WO2020065141A1] The present invention relates to an electric arc-extinguishing device (1) for an electrical protection apparatus comprising: - splitter plates (3) in parallel with one another and held together by two support elements (4), each splitter plate (3) comprising an electric arc inlet recess (6), each electric arc inlet recess (6) defining two branches (10) that each of the splitter plates (3) comprises, - an electric arc anti-restrike element (11) made from electrically insulating material, the extinguishing device (1) being characterized in that: the main face (12) comprises an upstream area (AM) and a downstream area (AV), separate from one another, the upstream area (AM) being located on the surface of the branches (10) and being defined by the edge (6') of the recess (6), and the downstream area (AV) corresponding to the remaining surface of the main face (12), the main face (12) comprises a positioning area (P) for positioning said at least one anti-restrike element (11), facing which said at least one anti-restrike element (11) is positioned, the positioning area (P) extending between a first median axis (M1) of the upstream area (AM) and a second median axis (M2) of the downstream area (AV), said at least one anti-restrike element (11) has a predetermined length (L1) configured so as to prevent the electric arc from returning after it has split.
