A circuit interrupter having at least two sets of contacts that are electrically connected in series such that when the at least two sets of contacts are opened, they are opened simultaneously. This functions to increase the distance between the sets of contacts as the distance is additive for the series connected sets of contacts, which increases the arc voltage for breaking any arc that may form between the individual sets of contacts more effectively. The contacts are configured such that there is a lateral sliding action as the contacts close, which functions to "wipe" the respective contact surfaces to remove any debris or contamination that may be on the surfaces.
