LINETRAXX® RCMA420
Het AC/DC gevoelige lekstroombewakingsapparaat RCMA420 wordt gebruikt voor bewaking van geaarde systemen (TN- en TT-systemen) waarin naast AC-lekstromen ook zuivere DC-lekstromen kunnen optreden die hoger zijn dan 6 mA. Dit zijn vooral elektrische apparaten met zesspuls-bruggelijkrichters of een enkelfase gelijkrichter met afvlakking, bijv. omvormers, laders, machines met frequentie geregelde aandrijvingen.
Door het instelbare vooralarm (50...100% van de ingestelde drempelwaarde In2) kan onderscheid worden gemaakt tussen voorwaarschuwing en hoofdalarm. Omdat de meetwaarde wordt geregistreerd via de meetspoel, is het apparaat vrijwel onafhankelijk van de nominale spanning en de stroom van de installatie.
