Measuring current transformers
CTUB101-CTBC... series measuring current transformers in combination with MRCDs convert AC
and DC currents into an evaluable measuring signal. They can be used in DC, AC, and 3(N)AC sys-
tems. The shielded measuring current transformers of the CTUB101-CTBC...P series also feature a
full magnetic shield to prevent nuisance tripping due to external influences.

The measuring range must be set according to the response values in the evaluator. It is
imperative to observe the manual of the respective measuring current transformer.
