Current Transformers

IACTXXI series

₩0 Sold out

The IACTXXI series consists of split-core current transformers designed for electronic measurement of AC waveform currents, ensuring galvanic isolation between primary and secondary circuits.

The small spacing for the physical size options (10mm/0.39",16mm/0.63", 24mm/0.94", 36mm/1.42") allows for flexible installation. Each CT size has a hinge and clipping mechanism that makes it easy to close the CT in tight situations.  The CT comes with an 8-foot long twisted pair wire and a 2-pin CT plug.

Specifically tailored for SENSWAY IoT meters with embedded CTids, the ratio error and phase displacement of the IACTXXI series have been rigorously tested and meet the accuracy requirements of the IEC 61869-2 Class 1.0 and IEEE/ANSI C57.13 Class 1.2 standards.
