Function

QCT-C-xx three-phase current transformers measure the load currents of an electrical system and send the data to meters via an RJ12 output. With a wide measuring range, QCT-C-xx three-phase current transformers cover the entire current range from 5 to 1000 A with just 4 references. They are combined with COUNTIS P44-xQCT meters.
Thanks to a complete range of accessories, they can be installed in any type of cabinet.

Conformity to standards

IEC 61557-12
IEC 61869

References

QCT-C-xx is available in 4 versions
