An electrical contactor (10) is provided comprising a first terminal (12) having a fixed member (26) with at least one fixed electrical contact (28); a second terminal (14); at least one electrically-conductive movable arm (38) in electrical communication with the second terminal (14) and having a movable electrical contact (42) thereon; and an AC dual-coil actuator (50) having a first drive coil (56) drivable to open and close the movable and fixed electrical contacts (42, 28), and a second non-drive coil (58) feedback connected to induce a reverse flux to temper and stabilise a nett flux, thereby enabling control of a delay time of the opening and closing electrical contacts (42, 28) so as to be at or adjacent to a zero-crossing of an associated AC load current |
