Zusammenfassung:	A moving seal for an air circuit breaker provides an arc creepage surface that is positioned between a pair of separable contact assemblies when the moving seal is fit into an inlet of the arc chamber. The arc creepage surface has a surface contour that increases a length of an arc travel path between the separable contact assemblies, relative to a straight line distance between of separable contact assemblies.
