Power Circuit Breaker - Operation and Control Scheme | PEguru

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 52a contacts are closed. The 52a contact follows the status of the breaker. A form ‘b‘ contact represents a Normally Closed (N.C.) contact. It operates exactly opposite of what an ‘a’ does. When the breaker is open, the 52b contacts are closed. When the breaker is closed, the 52b contacts are open. With the 52a contact in the trip circuit (as shown in the scheme above), once the breaker opens, this contact opens too. Now no matter what the relays do, the trip coil is isolated. On...Get price
