RCM 201-ROGO

Applications

  • Standards-compliant Type A measurement on the busbar

    The RCM 201-ROGO residual current monitoring device complies with standard DIN EN 62020 and is used for monitor systems and consumers that must be operated without interruption. It is ideally suited for monitoring residual currents in TN-S systems. The main application of the stand-alone device is the measurement of Type A residual current for large cross-section or busbar systems. In combination with a Rogowski coil (included in the scope of delivery), the user enjoys flexibility even in confined spaces and also benefits from the retrofitting capability of the measurement device.

  • Flexible measuring current transformer in different lengths:

    • Space-saving and fast installation
    • Easy retrofitting in existing systems
    • No shutdown of the system required for installation
    • Analog output for external measurement devices provided
  • Meaning of Typ A, B, B+
