Doepke The experts in residual current protection technology DATA SHEET DRCA 1 CT 140 Transducers for DRCA 1 residual current analysis system Article No. 09352057 T Function Transformers in combination with evaluation units are suitable for measuring and/or analysing residual currents. The transducers of series DRCA 1 CT together with the DRCA 1 detection unit form a residual current analysis system. Other detection units cannot be operated with this type of transformer. The transformers have a wide detection frequency range. Features suitable for detecting residual currents from 10 Hz to 100 kHz, dierent internal diameters available for adjustment to the cable to be monitored, robust plastic housing, reverse polarity protected connection socket for measuring cable Mounting The devices are mounted on stable substrata using the supplied mounting brackets. any installation position Applications Transformers from series DRCA 1-CT are used in combination with DRCA 1 analysis system. Notes The measuring bushing transformer should be mounted in such a way that it measures within the immediate vicinity of the RCD in question.
