Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A moving seal for a circuit breaker, said circuit breaker including a housing assembly and a number of pairs of separable contacts, said housing assembly defining a number of generally tubular pole chambers, wherein each pair of said separable contacts includes a stationary first contact and a movable second contact, wherein each second contact moves between an open, first position and a closed, second position, each pair of separable contacts disposed in an…
