USE OF AN ELECTRICAL CONTACT MATERIAL FOR BLOWING AN ELECTRIC ARC

摘要

The present invention relates to the use of a material comprising a conductive metal matrix and magnetic entities representing between 8 and 80% by weight of the material and comprising hard magnetic phases, said magnetic entities being non-magnetized but capable of being magnetized in an average orientation defined by the direction of a magnetic field applied to said material, in order to blow an electric arc between two electrical contact pads, at least one of which comprises said material.
