RCMA420

AC/DC sensitive residual current monitor for TN and TT systems (AC, DC and pulsed DC currents), smooth DC fault currents or residual currents continuously greater than zero
  • LCD seven segment display
  • six-pulse rectifiers or one way rectifiers with smoothing, such as converters, battery chargers etc.
  • Two separately adjustable response values 10…500 mA
  • prewarning stage (50…100 % of the set response value IΔn2) allow to distinguish between prewarning and alarm
  • Nearly independent of the load current and the system voltage
  • An external BENDER current transformer is required for operation.
