Ground Fault Current Sensors

Ground Fault Current Sensors_title.jpg

Taehwatrans’ ground fault sensors are used in a wide range of applications monitoring AC circuits, from operating a circuit breaker to sending an alarm contact to a programmable logic controller. As electrical vehicle (EV) takes up more market shares in automotive industry, ZCT finds new opportunities in EV charging cable and station applications.

  • GFCI outlet receptacle (Wall socket)
  • AFCI outlet receptacle (Wall socket)
  • ALCI power cord
  • Differential (mA) current sensor
  • Ground neutral sensor
  • EV Charging Plug & Cable
General Features
  • Close to zero load shift
  • Excellent balance properties
  • Precision output voltage

  • Minimal thermal variance
  • RoHS compliant
Differential Current Sensor

To sense the minimal differential current detected by the ground fault which could be caused by the difference between the line current and the grounded neutral current.

Ground Neutral Sensor

To sense the unexpected high level of current magnitude change or overload current occurred from the arc by the fire or the short circuit.
