SDH Type Current Transformer

Introduce:

SDH series current transformers can be used to test, control, display and record the operation of electrical equipment and protect equipment from damage.

In the AC circuit with rated voltage lower than 720V and frequency of 50-60Hz, this product can also be used for matching mine transformers.

Features:

  • The structure of the self-locking, safe, easy to install, portable.
  • Wide inner window, allowing clamping of big cables or bus-bars.
  • Wide range of sizes to accommodate all the existing installations.

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.
