Black Split Core Current Sensor Magnetic Circuit Structure High Precision

SCTK681A Series 5A-630A RoHS Split Core Current Transformers with 0.333VAC or 0-500mA output

SCTK681A series split-core current transformer

  • Test range: 5 to 630A AC input, output of 0 to 0.333V, 0 to 500mA
  • Has been specially designed to facilitate their installation in new or already existing net works.
  • They may be installed without opening any cable or bus-bar circuit.
  • An internal precision resistor across the secondary winding of the CT provides a low safe voltage output.
  • It can save time and the installation costs.


Applications:

  1. Relay protection device.
  2. Current and power measurement for electric motors, lighting, air compressor,heating and ventilation system, air-condition equipment and automation – control system.
  3. Current measurement, monitoring and protection for electrical wiring and equipment.
