Page 4: Purpose
1.PURPOSE E3-LE-03MQ CT is a static (electronic) calibrated electricity meter of single-phase or three-phase alternating current in a direct system. It is used for reading and recording of consumed electric energy and mains parameters with remote readout via a wired RS-485 network. The meter works with current transformers (CT) with 1 A or 5 A secondary current. -
