Abstract
The present invention relates to a control device and a method for controlling an electromagnetic actuator for electric circuit breakers, said actuator comprising a trip magnet (12) and a closing magnet (14) for actuating the movable contact system of the circuit breaker. The control device (10) comprises a power source (16) connected to the trip magnet (12) and to the closing magnet (14). The control device (10) also comprises a first switching means (18) connected between the power source (16) and the trip magnet (12), and a second switching means (20) connected between the power source (16) and the closing magnet (14) for connecting or disconnecting the power supply to the trip or closing magnet (12, 14), respectively. The control device (10) comprises at least one detector (22, 24) to detect the contact positions of the trip magnet (12) and the closing magnet (14). The detector (22, 24) is connected to a control unit (26) which controls closing or tripping of the switching means (18, 20).
