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.
