Zusammenfassung:	An arc extinguishing composition including an arc-quenching metal hydrate (herein defined as a metal compound that produces water vapor (H 20) when in contact with an electrical arc), and one or more binders. The compositions contain an arc-quenching metal hydrate compound, such as Mg(OH) 2, with or without a second arc-quenching compound, such as melamine, and these metal hydrate-containing compositions are used in a method of extinguishing an arc by disposing the molded compositions along a path of an electrical arc, for contacting the arc.
