LMZJ Type Current Transformer

Introduce:

LMZ and LMZJ ranges of current transformers are mainly used indoors.

For a rated voltage of 0.5kV and below rated frequency of 50Hz AC circuit as the current energy measurement or relay use.

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 Current, power and energy monitoring device.
  • Relay protection device.
