LMK Type Current Transformer

Introduce:

In order to protect equipment from damage, LMK3 series current transformers are used in AC circuits with a rated voltage below 720V and a frequency of 50-60Hz.
This product can also be used in matching mine transformers.

 

Features:

  • 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.
