摘要： The invention relates to a switching device for short-circuiting and earthing at least two phases in an electric power network. The device comprises a first phase contact (1), a second phase contact (2) and an earthed, movable contact (4), which can, on the one hand, assume a first position, where the contact (4) is insulated from the phases, and, on the other hand, a second position, where the contact is connected to the phase contacts and thereby earths and short-circuits the phases. The device is characterized in that the first phase contact and the second phase contact are axially displaced from each other and that they are disposed around the movable contact, and that the contact is cylinder-shaped and comprises two circumferentially disposed contact areas (18, 19; 34, 35), which are axially displaced from each other and intended to connect to the phase contacts in the second position, so that the phases are short-circuited and earthed via the contact, and that the device comprises electrically insulating areas (32; 33), which are adapted to abut against the phase contacts in the first position.

摘要： The invention relates to a power switch configured for the purposes of preventing accidental arcs in a low-voltage switchgear. The invention provides the power switch with an overcurrent evaluation means responding to an accidental arc produced in the switchgear. An overcurrent signal 104 arriving from the arc monitoring system LBS (occurrence of the flash of an accidental arc) is linked to the signal 103 for triggering the control means via a first evaluation means S1, 182, 63 for evaluating the intensity of the overcurrent originating from the accidental arc. The means 70 for triggering the power switch is activated, on issuing of a turn-off pulse 200, merely if the signal 180 from the current detection means 80 is above a preadjustable threshold S1. The invention allows the power switch to cut off more rapidly an overcurrent based on an accidental arc.
