Power distribution | Power Generation and Distribution

Ten years later, the Siemens puffer circuit breaker brought the second generation of SF 6 circuit breakers onto the market. The modular system used in all Siemens SF 6 circuit breakers ensured very reliable operation and easy maintenance. These circuit breakers used sulfur hexafluoride (chemical formula: SF 6) as the arc quenching medium. It was blown onto the contacts and interrupted the arcs caused by switching.Get price
