Abstract (en)

[origin: DE4434074A1] The vast majority of multi-pole contactors have an a.c. drive consisting of a magnet coil, a magnet yoke with eddy current rings and a movable magnet armature. Uneven burning of the contacts connected to the phases of the three-phase mains (L1, L2, L3) is prevented according to the invention by a phase changeover device (40, 60) which alternately connects the control phase for the magnet drive (50) to one of the phases (L1, L2, L3) of the main circuit.
