    Claims (6)
    [1]
    Formula of the invention: 1 "Direct-link electromagnet designed to interact with contactor breakers, comprising a fixed core, a movable armature connected to contactor breakers, made in the form of a concentric core with a field winding located on the fixed core with at least one pole piece at the armature made in the form of blades, separated from the fixed core by a longitudinally variable air gap, a node for ensuring the armature returns to the inoperative position, creating a longitudinal force on the armature, as well as a concentric compensation spring mounted outside the fixed core opposite the variable air gap, while the compensation spring is set so that it interacts with the anchor only on part of its course, - characterized in that, in order to expand the scope of use by providing To work with a different number of breakers, the compensation concentric spring is equipped with a thin U-shaped bracket, the parallel branches of which interact with the sides of the pole end of the armature, while the sections of this bracket located between the branches and the center of the elastically deformable cross-connecting them interact in longitudinal direction with inclined tides of an adjustable rotating cam mounted concentrically to the core of the armature.
    :
    [2]
