The Accu-CT® family of standard and revenue-grade, split-core current transformers offer outstanding linearity, very low phase angle
error, easy one-handed opening and closing, with a safe 333 mVac low voltage output. The standard Accu-CT meets IEEE C57.13 class 1.2, and when ordered with Option C0.6 it meets IEEE C57.13 class 0.6 accuracy standards. Each option C0.6 CT ships with a certificate of calibration.
Designed specifically for the WattNode® energy and power meters, the Accu-CT is available in two window opening sizes. The
ACTL-0750 has a window opening of 0.75” x 0.75” for current measurements up to 250 amps while the ACT-1250, with its unique
oval shaped window opening of 1.83” x 1.25” is designed for loads up to 600 amps. Both models are available in standard and revenue-grade
accuracies with exceptional low-end accuracy from 1% to 120% of primary rated current - 10x better than traditional CTs
