Differential current monitoring devices (RCM) reliably detect fault and differential currents and report them without switching off the system. They are used where it is not possible or desired to switch off the system. DCTR series differential current monitors are compact and easy to install. The evaluation device is already integrated. The device continuously detects the amount of current leakage and error currents and transfers them proportionally as 4-20 mA signal or over Ethernet, depending on the version. A potential-free changeover switch switches when the trigger threshold is exceeded. A multi-colored LED signals the status. Monitors with the differential current characteristic A detect sinusoidal AC and pulsating DC fault currents. Standard design devices are designed for monitoring circuits with a rated voltage up to 690 V and a rated frequency of 50 to 60 Hz. Properties: Suitable for detecting fault currents of the type A; monitored frequency range 50 Hz - 60 Hz; rated voltage of the monitored circuit up to 690 V; alarm relay with potential-free changeover contacts; auxiliary voltage-dependent; compact, robust plastic casing; easy mounting; Mounting type: The fixing is done on stable surfaces or a mounting plate by means of the available screw points; areas of application: The monitoring device is suitable for use in power supplies of purpose-built and industrial plants with TN-S, TN-C-S networks and IT networks, e.g. in server rooms of data centers, in laboratories, in the automotive industry and in connection with air-conditioning systems, printing machines and packaging machines; the use in TN-C networks and DC networks is excluded as well as the monitoring of plants. Where electronic equipment can cause smooth DC fault currents or fault currents with frequencies not equal to the rated frequency of the RCCB; Notes: RCM must not be used to implement the "Automatic power supply cut-off" protection measure in accordance with DIN VDE 0100-410 (an RCM does not replace an RCD).
