Forms of ContactCircuit Breaker Trip SchemeCircuit Breaker Close SchemeSummaryBefore explaining what each device in the scheme does, understanding the different forms of auxiliary contact is necessary. Every breaker comes fitted with an auxiliary switch. It is mechanically linked to the breaker's trip close mechanism. Within the auxiliary switch case you can have either form 'a' contact (a.k.a. 52a per ANSI) or form 'b' (a.k.a. 52b). A form 'a' contact represents a Normally Open (N.O.) contact. Thus when the breaker is open, its 52a contacts are open. When the breaker is closed, the 5…See more on peguruEstimated Reading Time: 7 minsComparison Between Vacuum and SF6 Circuit Breaker electrical engineering portal/comparison between vacuum and sf6 circuit...2018/8/29SF6 circuit breakers In an SF6 circuit breaker, the current continues to flow after contact separation through the arc whose plasma consists of ionized SF6 gas.
