Sentran Model 4LSG split current transformer is a collection of multiple window sizes

  • Window sizes are available in a range of current inputs
  • This split core CT is meant to be installed only on insulated conductors
  • The millivolt output version uses an internal calibration resistor to set the output voltage
  • The millivolt output version is limited for some input currents due to internal coil winding room
  • The group is rated CAT III for field installation and termination to any UL certified meter
  • The 4LSG series is considered stand-alone UL listed products rather than a recognized component
  • Therefore, these current transformers can be field installed without further system testing with compatible instrumentation Specifications
    • Input Current: AC current, sine wave, single phase 50/60Hz
    • Output 0.333 Vac
    • Voltage Rating: 600VAC, rated CAT III
    • Bandwidth: 50Hz to 400Hz
    • Standard Accuracy: Class 1 per C57.1301 IEC 61869
    • Optional Accuracies: Class 0.5 per Table 201 IEC 61869
    • Special Order Accuracy: Class 0.2 per Table 201 IEC 61869
    • Output Resistance: < 100 Ω typical Interface Resistance: Must be > 100 kΩ
    • Altitude: Up to 2000 meters
