    Abstract: Discloses an arc chute having spaced sidewalls of a first insulating material and arc runners having most of their active surfaces of a refractory metal. Between one of the runners and the sidewalls are two face plates of a second insulating material, such as glass-bonded mica, that is characterized by low gas evolution and greater surface resistivity than said first material under high humidity conditions. The face-plate surfaces adjacent an arc are shielded from the arc by a thermally-sprayed coating of refractory ceramic insulating material on said surfaces.

    Abstract: DISCLOSES AN ARC CHUTE COMPRISING INSULATING SIDEWALLS AND SPACED-APART METAL RUNNERS PROVIDING PATHS ALONG WHICH THE TERMINALS OF AN ARC TRAVEL AS THE ARC MOVES INTO THE CHUTE. ONE OF THE RUNNERS COMPRISES A STRIP OF CONDUCTIVE MATERIAL AND A COATING OF THERMALLY SPRAYED REFRACTORY METAL BONDED

    TO A SURFACE OF THE STRIP TO DEFINE AT ITS EXPOSED SIDE AN ARCRUNNING SURFACE.
