Abstract: A method performed in a control unit for opening a contactor device. The contactor device includes a carrier being movable between a closed position in which a current is allowed to flow in a current path and an open position in which the current path is broken. The control unit is configured to enable the movement of the carrier between the closed position and the open position by energizing a coil of an electromagnetic circuit. The method includes: initiating the opening of the contactor device by de-energizing the coil, wherein the de-energizing includes using a demagnetization circuit including a discharge element, the discharge element being arranged to consume energy in the coil; bypassing, at a first point of time, the discharge element; and re-energizing the coil.

Abstract: A method of controlling a mechanical contactor including at least one pair of contacts for conducting a mains current (Im) when the contactor is in a closed position, and an electromagnet arranged to close the contactor, and maintain the contactor in the closed position, by forcing the pair of contacts towards each other when a control current (Ic) runs through a coil of the electromagnet. The method includes, while the contactor is in the closed position, obtaining an indication of unintentional separation of the contacts, and in response to the obtained indication, opening the contactor and maintaining the contactor in an open position by turning off the control current.

Abstract: A switching device for breaking an electric current including a main contact carrier, movable and stationary main contacts, the movable contact attached to the main contact carrier, an arcing contact carrier, a movable and stationary arcing contacts, the movable arcing contact attached to the arcing contact carrier and the stationary arcing contact arranged in parallel with the stationary main contact, and an actuating unit for the main and arcing contact carriers between open and close position at an actuating distance, wherein there are separation distances between the stationary and movable contacts of the main and arcing contact units respectively when the current is interrupted. The switching device further includes a first rack and a first gear for actuating the arcing contact carrier so that, when interrupting the current, a separation distance between the arcing contacts is longer than a separation distance between the main contacts.

Abstract: Electrical contact system with a first and a second contact (1, 5), each having a contact surface (4, 8). The first electric contact (1) has a mesostructured electric contact portion (14) with a plurality of slots (15) and ridges (16) formed between neighboring slots (16) of the plurality of slots (16). These slots (15) and ridges (16) extend in a direction running transversely to said switching plane (X-Z) form a plurality of current paths (16). The current paths (16) are inclined to the first contact surface (4) at a first angle (17) measuring less than 60 degrees such that an interruption current (12) flowing through the mesostructured electric contact portion (14) and through an electric arc (11) extending in between the first contact surface (4) after lifting the first contact surface (4) off the second contact surface (8) pushes said electric arc (11) in the direction of the apex of said first angle (17) from a first position (18) to a second position (19).
