a method and apparatus in a control system for an electromagnetic contactor for reducing multiple re - ignitions incorporates a regulated source of electrical power coupled to a contactor actuating coil through a controllable switch . the switch is used to regulate coil current to a desired value whereby opening time of the contactor can be determined within a defined range . alternating current through tips of the contactor is monitored and each zero crossing of the current wave form is determined . the control system responds to a command to open the contactor tips by coordinating such opening with the zero crossings of the current wave form whereby the contact tips separate within a predetermined phase angle prior to a zero crossing . the system also includes apparatus for detecting a fault current of the alternating current in the contact tips and for inhibiting operation of the contact tips for a predetermined time interval in order to allow fuses to clear the fault prior to opening the contactor .
