Doepke 09342631 DCTR A 035/0,3-I residual current transformer

Residual current monitoring devices (RCM) reliably detect fault and residual currents and report them without switching off the system. They are used where switching off the system is not possible or desired. Residual current monitors of the DCTR series are compact and easy to install. The evaluation device is already integrated. The device continuously detects the level of the current leakage and fault currents and, depending on the variant, outputs them proportionally as a 4-20 mA signal or via Ethernet. If the response threshold is exceeded, a potential-free changeover contact switches. A multi-colored LED signals the status. Monitors with residual current characteristic A detect sinusoidal alternating and pulsating direct residual currents. Standard devices are designed for monitoring circuits with a rated voltage of up to 690 V and a rated frequency of 50 to 60 Hz. Properties: suitable for detecting type A fault currents, 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 housing, easy installation, type of installation: The device is attached to load-bearing surfaces or a mounting plate using the existing screw points, areas of application: the monitoring device is suitable for use in power supplies of functional buildings and industrial plants with TN-S, TN-CS networks and IT networks, e.g. in server rooms in data centers, in laboratories, in the automotive industry and in connection with air conditioning systems, printing machines and packaging machines. Use in TN-C networks and direct current networks as well as the monitoring of systems is excluded. in which electronic equipment can cause smooth DC residual currents or residual currents with frequencies not equal to the rated frequency of the RCCB. Note: RCM must not be used to implement the protective measure of automatic shutdown of the power supply in accordance with DIN0100-410 (an RCM does not replace an RCD).
