ACTL-0750 Split-Core CT


The Accu-CT revenue grade, split-core current transformer offers outstanding linearity and very low phase angle error with easy one-handed opening and closing, even wearing gloves.

The standard Accu-CT meets IEEE C57.13 class 1.2 and when ordered with Option C0.6 it meets class 0.6 accuracy standards. Each Option C0.6 CT ships with a serialized calibration certificate.

CT Info: 5A to 250A 0.75 x 0.75 in.

The patented Accu-CT split-core current transformer technology delivers exceptional linearity and low-end accuracy. Developed specifically for solar inverter, variable speed motor drive, and other applications where there are large variations in current. The 100:1 turn down ratio (highest to lowest current) of Accu-CTs is ten times better than industry standard CTs. The unique one-handed opening and closing mechanism makes installation a snap.

ACTL series CTs are available in both standard and revenue grade accuracy models. Revenue grade models ship with a serialized certificate of calibration.
