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 of Accu-CTs is ten times better than industry standard CTs
  • The unique one-handed opening and closing mechanism makes installation a snap
  • Square 0.75 in. Window Opening
  • Safe: built-in burden resistor provides 0.333 Vac voltage output at the rated full scale current—no shorting blocks needed
  • UL 2808 Listed meets 2017 NEC code requirements for field installed current transformers
  • IEEE C57.13 and IEC 60044-1 accuracy: over full temperature range and down to below 1% of rated current
  • Exceptionally low phase angle error: essential for accurate power and energy measurements
  • Glove-friendly: easy to open and install with one hand while wearing safety gloves
  • 333mV Output
    • With Option C0.6, the Accu-CT is calibrated and verified to meet IEEE/ANSI C57.13-2008 class 0.6 accuracy and IEC 60044-1 class 0.5 S accuracy and each CT is shipped with a certificate of calibration
    • When used on 50 Hz services, Option C0.6 must be ordered with Option 50Hz
    • Accuracy: ±0.50% from 1% to 120% of rated primary current
    • Phase angle: ±0.25 degrees (15 minutes) from 1% to 120% of rated current; ±0.50 degrees (30 minutes) below 0°C from 1% to 10% of rated current
    • IEEE C57.13 accuracy: class 0.6 from 1% to 120% of rated current
    • IEC 60044-1 accuracy: class 0.5 and 0.5 S from 1% to 120% of rated current
    • Note: The ACTL-0750-250 Opt C0.6 model specifications are valid only to 40°C
