ABSTRACT:
Contactor equipment with an operating magnet with an operating coil (CW) as well as an armature, which moves in dependence on the current through the operating coil. The contactor has control means (TR, CC, R1. R2, R3) which control the voltage supplied to the operating coil. During the closing operation of the contactor, for utilization of the current-reducing effect of the change of inductance taking place because of the movement of the armature during a closing operation, a voltage is supplied to the operating coil which is substantially constant during the closing operation and independent of the current of the operating coil. After a completed closing operation, the current is controlled through the operating coil in accordance with a reference value.
