Protective device against overloads and short circuits for electrical installations

摘要

The protective device against overloads and short circuits for electrical installations.The invention relates to a protection device for electrical installation, comprising at least two electrodes between which an electric arc can form, and a device for breaking up (6) the arc, extending between one end (6a), and an upward downward edge (66), with a The region of entry (and) to the arc at the end (6a) of the ascendingAt this point, the arc enters the shearing device (6).The device of rupture (6) comprises insulation devices (10) that allow the arc to enter the device (6), while breaking form an obstacle to get out to the arc.The device is characterized by the fact that the insulation devices (10) are formed by one or more flexible strips embedded to form a barrier between the electrodes and the insulation partial upward edge (6a). The invention also relates to devices for protection against overload and short circuit.
