摘要

A fused electrical disconnect device (1, 100, 110), in particular for direct current, with a magnetic module for blowing out of the electric arc, wherein said separating device at least one housing (2, 200, 210), the at least one interruption pole, the at least one with a first movable contact (5, 500, 510) together operating first fixed contact (3, 300, 310), wherein this stationary and this movable contact in the form of sliding contacts, wherein said first movable contact is designed, in order to be in a so-called junction plane (p) to move and with the said first fixed contact a first separated-sector (z1) to determine in which, in the case of the opening of the circuit a first electric arc (e1), wherein said magnetic module at least one first permanent magnet (11), in the immediate vicinity, with respect to the first separation region (z) is arranged and aligned parallel to the side of said junction plane (p) to generate a magnetic valid excitation vector, so that the induced electromagnetic force (fe) the first arc (e1) in a to the side of said junction plane (p) vertical direction, depending on the polarity of the said first magnet and / or of the said current independently in one direction or the other, to be displaced and stretched, characterized in that the said first permanent magnet in a first insulating support (20) is accommodated, which protects it from the arc, and in that it has in the said housing symmetrically with respect to the said junction plane (p) is positioned such that the induced electromagnetic force (fe) being perpendicular to two parallel, symmetrically with respect to the said junction plane (p) disposed walls of the housing (2, 200, 210) of said electrical disconnect device (1, 100, 110), the cooling and the erasing of the arc conveying.
