Description

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.

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.

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.
