Abstract
An electrical switch including a neutral contact adjustment system adapted for adjusting a position of a neutral contact opening surface relative to at least one phase contact opening surface such that the neutral contact adjustment system has a first operating state which is adapted to provide a simultaneous break operation in which a movable neutral contact disconnects simultaneously with at least one movable phase contact during an opening event, and a second operating state which is adapted to provide a late-break operation in which the movable neutral contact disconnects later than the at least one movable phase contact during the opening event.
