DMRCD 1 B+
Details
modular residual current device Type, 85 V - 264 V AC
suitable for detecting type B+ residual currents, monitored frequency range 0 Hz (DC) – 100 kHz, rated residual operating current can be adjusted at five levels, large selection of connectible residual current transformers, rated voltage of monitored circuit up to 690 V, with alarm relay, the response thresholds for the pre-alarm can be set from 10 % to 90 % of the response threshold for the alarm, the set value for the pre-alarm threshold is displayed as a continuously lit LED on the bar display, two potential-free changeover contacts for pre-alarm and main alarm, selectivity adjustable at ten levels, dependent on auxiliary voltage, compact, robust plastic housing, easy mounting, complies with DIN EN 60947-2 / VDE 0660-101, DIN VDE 0664-110 (B+), VDE 0100-410 / IEC 670364-4-41 and VDE 0100-530
quick fastening to mounting rail, any installation position
The monitoring device is suitable for use in power supplied to purpose-built buildings and industrial facilities with TN-S, TN-C-S networks, IT networks and direct current networks, such as in server rooms for data centres, laboratories, in the automotive industry and in conjunction with photovoltaic and UPS systems with frequency converters without transformers, air conditioning systems, frequency converters, switching power supplies, high-frequency converters, printing machines and packaging machines. , Suitable for monitoring DC circuits and systems in which electronic equipment may generate smooth DC residual currents or residual currents with frequencies not equal to 50 Hz.
Residual currents are detected separately by external residual current transformers from series DCT, which are ordered separately. No more than one transformer can be operated on one evaluation unit. The maximum cable length from the control relay to the transformer is 10 m. The VDE certification is only fulfilled with approved switch-disconnector combinations and undervoltage trips (see DMRCD operating instructions). To meet DIN VDE 0100-410, the electrical system must be isolated from the mains by an external isolating device with a response time of less than 15 ms.
