  • Electrical switching device for fault-current, overcurrent and short-circuit current position
    Patent number: 7088207
    Abstract: An electrical switching device for fault-current, overcurrent and short-circuit current protection, has a contact point in a current path and a switching mechanism for permanently opening the contact point. The switching device further has a configuration for detecting the fault current, the overcurrent and the short-circuit current, and contains two permanent magnets and a core. The core is disposed between the like poles of the permanent magnets which point toward one another and one of which is fixed and the other is guided such that it can move. The permanent magnets are at least partially surrounded by a coil through which a fault, an overcurrent or a short-circuit current flows. When a current flow occurs in the coil, the magnetic field is changed causing a relative movement of the moving part, and the movement is transmitted to the contact point.
