The RCM 202-AB is employed with current transformers connected for the measurement and monitoring of residual currents of the types A, B and B+ in TN and TT systems (grounded AC systems)
Residual current measurement using up to two connected current transformers (compatible with all Janitza residual current transformers)
Transformer connection monitoring for wire break orshort circuits per channel
Acquisition, evaluation and monitoring of residual currents of types A, B and B+ to IEC 62020
Acquisition of sinusoidal AC fault currents with frequencies of up to 20 kHz (type B+)
Acquisition of purely DC currents
Measured and extreme values memory with time stamp
Advantages
Residual current monitoring in industrial installations
Computing centers
Hospitals
Standards compliant measurement to minimise DGUV V3
