  • Arc contact element for electrical apparatus production method thereof, corresponding contact assembly and electrical apparatus
    Publication number: 20050236370
    Abstract: This arcing contact element (10, 18) is capable of occupying an initial position in which it is in contact with another arcing contact element (18, 10), as well as a second position, in which it is separated from this other arcing contact element so as to allow interruption of the current. This element consists of carbon fibres embedded in a matrix which includes at least one electrically conducting material linked to graphite.
