Abstract (en)
This operation control device for a contactor including a pull-in coil (1) and a coil (2) for holding a moving assembly in active position, the supply to which is governed by control means (6, 7), is characterised in that the control means include separate means (6, 9, 10) for control of the supply to the coils, receiving, as input, information on the power supply voltage of the contactor, in order: - simultaneously to feed the two coils (1, 2) during engagement of the operation of the contactor; - cutting off the supply to the pull-in coil (1) at the end of a defined time after the engagement of the operation of the contactor; and - again supplying the pull-in coil (1) in the event of a defined fall in the power supply voltage of the contactor during the operation of the latter. <IMAGE>
