LE-03M CT

Electric energy meter, 

3-phase

The LE-03M CT is a static (electronic) calibrated electricity meter 

of three-phase alternating current in a semi-direct system.

Indicator is designed to work with current transformers for pri-

mary current Ip from 5÷6000 A and secondary current 5 A. The 

maximum current measured value of the system is determined 

by the primary current Ip applied CT (current transformer). 

The user has the ability to set the index value used gear ratio, 

which allows you to indicate the actual value taken by the elec-

tricity system.

Serial RS-485 and implemented Modbus RTU communication 

protocol allows the indicator used in networks for remote re-

ading of data.

Do not dispose of this device in the trash along with other waste! 

According to the Law on Waste, electro coming from households free of charge and can 

give any amount to up to that end point of collec� on, as well as to store the occasion of 

the purchase of new equipment (in accordance with the principle of old-for-new, regard-

less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the 

environment and human health.
