LE is a static (electronic) calibrated indicator of three-phase alternating current electricity in a semi-indirect system. The indicator is designed to work with current transformers with a primary current protection degree in the range of 5-6000A and a secondary current of 5A. The maximum measured current of the system is determined by the value of the primary current. Degree of protection of the current transformer used. The user has the option of setting the ratio value of the transformers used in the indicator, which allows the indication of the actual value of electricity consumed by the system.
