Abstract (en)
[origin: CA2847457A1] The invention relates to, inter alia, an electromagnetic drive (10) for an electrical switch (20), in particular an electrical circuit breaker, with at least one movable armature (60), which can implement a lifting movement along a predetermined pushing direction (P), can be connected indirectly or directly to a movable switching contact (21) of the switch (20), and, in a closed position (61), closes a magnetic circuit (M1, M2) of the drive (10) at a first armature-side stop face (62) with a first magnetically conductive yoke part (100) of the drive (10) and at a second armature-side stop face (63) with a second magnetically conductive yoke part (105) of the drive (10), with at least one permanent magnet (90, 95), which produces a magnetic field for the magnetic circuit (M1, M2) and a holding force for holding the armature (60) in the closed position (61), and with at least one coil (80), which is arranged in such a way that a magnetic flux can be brought about by a current flow through the coil (80), which magnetic flux is directed in the same direction as or in opposition to the magnetic flux of the permanent magnet (90, 95) in the magnetic circuit (M1, M2), wherein the electromagnetic drive (10) provides the possibility of a readjustment state after installation by virtue of self-adjustment of the position of the first yoke part (100) and the second yoke part (105) relative to one another being possible as a result of the magnetic force of the permanent magnet (90, 95), and wherein the yoke parts (100, 105) can be brought into a fixedly installed state, in which the alignment of the yoke parts (100, 105) is fixed independently of the further positioning of the armature (60).
