ABSTRACT:
A single pressure sulfur hexafluoride circuit breaker has ring-shaped arcing contacts fixed relative to one another and a magnetic coil electrically connected in the arcing circuit to create a magnetic field for spinning an arc between the arcing contacts. The circuit breaker includes a main circuit and a shunting circuit with stationary and movable contacts arranged so that the main contacts open before the shunting contacts and that the arc drawn between the shunting contacts upon their separation is transferred onto the arcing contacts.
