 LMZJ1 Series current transformer


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.

They’re pouring type current transformers, the installation method uses a fixed plate.

Features

1:Safe, easy to install, portable
2:Wide inner window, allowing clamping of big cables or bus-bars
3:Wide range of sizes to accommodate all the existing installations

Applications:

1:Current measurement, monitoring and protection for electrical wiring and equipment.

2:Current and power measurement for electric motors, lighting, air compressor, heating and ventilation system,

air-condition equipment and automation-control system.

3:Current, power and energy monitoring device.
4:Relay protection device.
