Abstract (en)
[origin: EP2685482A1] The device (1) has input and output terminals contacting the device with an electric line. A switching contact comprises a fixed contact piece (4) relative to a movable contact piece (5). The contact pieces are formed such that a light arc is formed between the contact pieces when opening the contact. The contact is electric conductively connected with the terminals over a current path. A current guide section of the path is formed and cooperated with the arc such that a resulting electromagnetic field is formed in which the arc interacts so as to drive the arc by the contact.
