Integration of internal arc-fault mitigation systems in power switchgear and controlgear assemblies (PSC assemblies) according to IEC 61439-2 Ingestion-build-58320 — Measuring Device1 Scope This document states requirements for integration and testing of IAMS in low voltage switchgear and controlgear assemblies power switchgear and controlgear assemblies according to IEC 614391 and IEC 614392 (PSC assemblies) to demonstrate their correct operation. This document does not address personnel safety or damage to the PSC assembly. These requirements are dealt with in IEC TR 61641 (see also 10. 10. 1). NOTE This document can be used as
