CTUB100 series consisting of measuring current transformer core and electronics module

The measuring current transformers of the CTUB100 series are combinations of measuring current transformer cores CTBC… and electronic modules CTUB10…, which convert AC and DC currents into an evaluable measurement signal. An evaluation of the measurement signal can be carried out with the help of devices of the series RCMA420/423, RCMS460/490 or EDS440/EDS441LAB. They can be used in DC, AC and 3(N)AC systems.

Residual Current Transformer Function

All-current-sensitive measuring current transformers can detect direct and alternating currents of different frequencies.
