    Jul 18, 2018The SF6 is what helps cut off the power when there’s an overload. An SF6 Circuit Breaker also boasts a very high level of electro-negativity, which means it also has a high absorption capacity for free electrons. When these electrons collide with the SF6 molecules, they get absorbed immediately and turned into negative ions, which weigh more.
