LINETRAXX® RCMA423AS

Product informatie voor LINETRAXX® RCMA423AS

The AC/DC sensitive residual current monitor RCMA423AS is designed for use in earthed systems (TN and TT systems) where DC and AC fault currents 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.


Two separately adjustable response ranges allow to distinguish between prewarning (IΔn1 = 50…100 % of the set response value IΔn2) and alarm ( IΔn2).
Since the values are measured with measuring current transformers, the RCMA423AS is nearly independent of the nominal voltage and the current of
the system being monitored.
