NSQ Type Current Transformer

Introduce:

NSQ Series current instrument transformers are designed for electric power systems of 50/60Hz rated frequency and rated voltage 0.66kV. They are used for indoor mounting.

Features:

  • The Current Transformers Are Made According To IEC-185 Standard.
  • Class Of Accuracy: 1.0 (see table)
  • Rated Voltage: 600V (see table)
  • Rated Sec. Current 5A(or 1A on reque.
  • Security Factor: FS5
  • Working Temperature Range: ABS plastic case, toally enclosed, built-in cover, and several ampere outputs at secondary side iron plate for fixing metal housing-2 pieces-1, iron bar and acrew for fixing copper bar-3 pieces.

Applications:

  • Current measurement, monitoring and piotection for electrical wiring and equipment.
  • Current and power measurement for electric motors,lighting,air compressor,heating and ventilation system,air-condition equipment and automation-control system.
  • Current,power and energy monitoring device.
  • Relay protection device.
