Integration and retrofit into switchboards according to IEC 614393WA air circuit breakers can be easily and flexibly integrated in power distribution boards according to IEC 61439. This standard describes in several parts the design verification for switchgear and controlgear assemblies and the responsibilities of the manufacturer and panel builder. Regardless of whether you are a panel builder, OEM or operator: the IEC 61439 standard is binding for all low-voltage power distribution boards and thus also requires compliance in the integration of the 3WA air circuit breaker in power distribution boards. This also allows open circuit breakers 3WL to be replaced quite easily. Learn in this White Paper what needs to be taken into account in the integration, along with other considerations.
