Beschreibung
Zusammenfassung:	The present invention relates to an electrical contact material comprising a matrix made of conductive metal and an unstable fraction incorporated into this matrix. The unstable fraction has the property of decomposing between the operating temperature of the electrical contact and the melting point of the metal with the release of a gas capable of destabilizing an electric arc.
