A contactor having main and auxiliary contacts and an arc quenching system including a blowout coil. The blowout coil is connected in series with a first and second set of auxiliary contacts and the resulting series combination connected in shunt around the main contacts. The second set of auxiliary contacts is arranged to open after the first auxiliary closes and before the main contacts close in order to remove the blowout coil from the circuit when the main contacts are carrying load current.
