The 245-kV breakers were the world's first of its kind to switch a short-circuit current of 80 kA.

Sulfur hexafluoride circuit breaker - Wikipedia principle. Current interruption in a high-voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF 6), having excellent dielectric and arc-quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity.
