    Abstract: A moving seal (150) for an air circuit breaker (8) provides an arc creepage surface (152) that is positioned between a pair of separable contact assemblies (20) when the moving seal (150) is fit into an inlet (16) of the arc chamber (13). The arc creepage surface (152) has a surface contour that increases a length of an arc travel path between the separable contact assemblies (20), relative to a straight line distance between of separable contact assemblies (20).
