residual current monitors DRCM 1 B+
Details
Residual current monitor Type, 85 V - 264 V AC
VDE-certified (DIN EN 62020), frequency characteristics as per DIN VDE 0664-110 (B+), 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, fixed response threshold of alarm between 75% and 100% of the set rated residual operating current (I∆n), adjustable pre-alarm threshold, alarm relay with two potential-free changeover contacts, selectivity adjustable at ten levels, dependent on auxiliary voltage, compact, robust plastic housing, easy mounting
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.
RCMs may not be used to realise protective measure ‘Automatic switch-off of power supply’ as per DIN VDE 0100-410 (an RCM does not replace an RCD). 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.
