摘要： The invention relates to an electrical contactor and to the associated contactor-closure control method The inventive electrical contactor (100) comprises: a removable conduction circuit (105), an actuator (110), a magnetic stator (115) and armature (120), and a controller (130). According to the invention, the actuator (110) is in mechanical communication with the removable conduction circuit (105), while the magnetic stator (115) and the magnetic armature (120) are disposed in field communication with one another and with an exciting coil (125) which responds to a coil current used to generate a magnetic field that is guided through the stator (115) and the armature (120). The above-mentioned controller (130) comprises a processing circuit (200) which is designed to control the coil current in response to the current and voltage in the coil (125), such that the coil current is controlled in response to the position and closure speed of the removable conduction circuit (105) before said circuit (105) closes as part of an open-to-closed movement.
