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. Differential current monitors with differential current characteristic B detect pulsating and smooth DC fault currents and AC fault currents up to 100 kHz. Devices in this variant operate with a fixed response differential current value of 0.3 A for the alarm relay. The DCTR outputs the measured differential current value proportionally as a 4 to 20 mA signal. Characteristics: Suitable for detecting residual currents of type B; monitored frequency range 0 Hz 100 kHz; rated voltage of the monitored circuit to 690 V; compact, robust plastic casing; easy installation; output of the differential current value via 4-20-mA interface; alarm relay with potential-free changeover contacts; operating voltage 24 V DC; Mounting type: The fixing takes place on stable undergrounds or a mounting plate by means of the available screw-on points; usage areas: The monitoring device is suitable for use in power supplies of purpose-built and industrial systems with TN-S, TN-C-S networks, IT networks and DC networks, e.g. in server rooms of data centers, in laboratories, in the automotive industry and in connection with PV and UPS systems with transformer-free inverters, air-conditioning systems, frequency converters, switched-mode power supplies, high-frequency converters, Printing machines and packaging machines; suitable for the monitoring of DC circuits and systems. In which electronic equipment can cause smooth DC fault currents or fault currents with frequencies not equal to 50 Hz.
