The eGauge ECS series CTs are split-core current transducers (CTs) with 36mm, 20mm, and 9mm openings

  • The eGauge ECSXX series CTs are split-core current transducers (CTs) with CTid technology
  • CTs are installed around current carrying conductors to measure amperage as part of a power metering system
  • Thanks to the split-core design, they are easily retrofitted to existing power systems and do not require the conductors to be disconnected
  • A 333mV output means no shorting blocks are required
  • All ECSXX CTs are UL2808 certified
  • eGauge CTs use CTid technology for auto-detection and have an onboard LED which can be used to identify which CT is connected to a given sensor port
  • This is useful if the CT leads cannot be traced
  • 1x ECS AC CT with built-in 8 foot leads and 2-pin plug affixed
  • An EG4xxx series meter is required for CTid functionality
  • Accuracy
    • 1% (ECSxx-yyy)
    • 0.5% (ECSxx-yyy-R)
