Abstract (en)
[origin: US4810841A] A current-limiting switching element, for whose at least one contact set comprising a movable and a fixed contact member, a device for providing an auxiliary magnetic field is arranged with an axis perpendicular to the direction of the extent of the movable contact member. It is provided that the direction of motion of the movable contact member lies in the direction of the axis of the device for providing the auxiliary magnetic field. The direction of the current to the contacts is chosen so that the movable contact member is subjected to a force repelling it from the fixed contact member with respect to the auxiliary magnetic field.
