RCM AC Residual Current Monitor is a combined residual current monitoring device for earthed power supply systems (TNC-S、TN-S and TT) residual current. It provides max 16 monitor channels and a panel mounting design that suits any electrical cabinet. LED screen displays various parameters, easy for the site engineer to diagnose and Insulation test.
This residual current monitor can optionally be carried out by a selected current transformer or temperature sensor for each channel detect parameter and alarm or trip threshold. Multiple RCM can combination with the circuit breakers for building MRCD applications. RS485 port of the RCM residual current monitoring can easily submit data to SCADA systems. OEM and ODM this residual current monitoring unit.
