Residual-current monitor

Blue Jay RCM-IV is a combined monitoring device for earthed power supply systems (TNC-S、TN-S and TT) residual current. It provide max 16 monitor channels, panel mounting design suit for any electrical cabinet. LED screen display various parameters, easy for site engineer diagnosis and Insulation test.

It can optionally be carried out by selected current transformer or temperature sensor for each channel detect parameter and alarm or trip threshold. Multiple RCM-IV can combination with circuit breaker for build MRCD applications, RS485 port can easy submit data to SCADA systems.
