KP-YCT-50 Clamp current transformer

In electrical energy measurement, some measurement circuits can't directly measure electrical parameters. Under this environment, the transformer must be transferred to measure.

Usage: Used for AC current, power, energy monitoring devices; relay protection devices; power factor correction devices.



  • Open-close installation, good consistency
  • Good linearity and high sensitivity
  • Good stability, light weight, multiple opening sizes for easy installation
  • Easy installation, opening and closing installation, no need to disconnect the system power
