Abstract (en)
[origin: EP2256771A2] The device has multiple arc chutes (5) provided with notches (8). An arc guide rail (9) comprises a rectangular section (10) facing an arc generation part (7). Another rectangular section (11) is adjacent to the former rectangular section. A trapezoidal side leg (12) is inclined to longitudinal axes of the former rectangular section, and extends far away from the longitudinal axes. The arc guide rail is connected with an arcing horn (34) with a fixed contact (3). Width of the former rectangular section is lower than width of the notches facing the arc generation part.
