Abstract
The support for the moving contact of a circuit breaker has a piston that is driven by arc gases generated by initial separation of the contacts through magnetic repulsion to rapidly open the contacts. A pair of telescoping shield sleeves that have aligned openings through which the moving contact is extended to close with the fixed contact are oppositely driven transversely to piston movement by the arc gases to cut off the arc.
