Application

Current Transformer For Electrical Safety

When a current exceeding 30 mA passes through the human body the individual will be at serious risk of a fatal electric shock if the current is not interrupted in a timely manner.

Besides, with the increasing ratio of electrical fire to fire, electrical fire has badly threatened people’s life and property security.

Electrical safety devices that shuts off an electric power circuit when it detects that current is flowing along an unintended path, such as through water or a person.

As a critical components for electrical safety device, we fully understand customers value the qualified supplier who can provide reliable performance of differential coils sensors.

  • Easily integrated into standard PCB sub-assemblies that are compliant with IEC61008, IEC61009 and IEC62423 requirements.
  • Detecting currents from 1~100 mA  -35 ~ +85℃.
  • Reliable performance gives the correct output that is proportionate to the differential current.

Differential Current Transformer For GFCI

Differential current transformer series are mainly applied to GFCI plugs, GFCI receptacles, connecting with various electric equipments.

  • Widely used for GFCI, floor heating and HVAC controls.
  • Sensing toroid using to sense minimal differential current caused by the ground fault
  • Grounded neutral toroid using to sense unexpected excessive current change or overload current caused by the arc resulted from the fire or the short circuit
  • Applied to the AFCI used in the air-condition
