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 52…See more on peguruEstimated Reading Time: 7 minsExplore furtherCircuit Breaker Control Schematic Explainedtestguy.netDifference between TOCs, MOCs and 52 breakersengineeringCircuit Breaker Schematic Diagram | Electrical AcademiaelectricalacademiaSeven design diagrams that every HV substation engineerelectrical engineering portalCircuit Breaker Operation (Operating Tripping Timeelectrical4uRecommended to you based on what's popular • FeedbackQA: Why is there a lock on my circuit breaker? structuretech/qa why is there a lock on my circuit breaker2015/6/16The answer is actually quite simple, but let me first explain why that locking device is there.
