The Accu-CT family of standard and revenue-grade, split-core current transformers offers outstanding
linearity, very low phase angle error, easy one-handed opening and closing, with a safe 0.333 Vac low voltage output.
The standard Accu-CT meets IEEE C57.13 class 1.2 and when ordered with the Option C0.6, both models of the Accu-CT meet IEEE
C57.13 class 0.6 accuracy standards. Both models are available in standard and revenue-grade accuracies with exceptionally low-end
accuracy from 1 to 120% of primary rated current – 10x better than traditional CTs. The ACTL-1250 can also be ordered with Option C0.3
for 0.3% accuracy readings. This is especially important when SREC requirements dictate system metering accuracies meeting or exceeding
ANSI C12.1-2008 specications.
Designed specically 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 ACTL-1250, with its unique oval shaped window
opening of 1.83” x 1.25” is designed for loads up to 600 amps. Each option C0.6 or C0.3 CT ships with a certicate of calibration.
The ACT series of high-accuracy split-core current transformers are UL Listed, certied by Underwriters Laboratory (UL) to meet the new
2017 NEC code requirement that CTs installed in the eld must be UL 2808 Listed under category code XOBA.
