  • AC/DC sensitive residual current monitor Type B acc. AS/NZS 2081:2011

  • Two separately adjustable response values 30…5 A

  • Frequency range 0…1000 Hz

Application

The AC/DC sensitive residual current monitor RCMA423AS is designed for monitoring earthed power supply systems (TN and TT systems) where smooth DC fault currents or residual currents continuously greater than zero may occur. These are in particular loads containing six-pulse rectifiers or one way rectifiers with smoothing, such as converters, battery chargers, construction site equipment with frequency-controlled drives. Currents in single conduc-tors can also be monitored by RCMA423AS.
