2/6
The E650 directly connected I&C meters record
active and reactive energy consumption in all threephase four-wire and three-phase three-wire
networks.
Range
E650 meters are the answer to a wide range of
specific needs: from the reliable commercial meter
to the complex measuring device with comprehensive additional functionality for sophisticated data
acquisition and flexible tariff control of large industrial customers.

E650 Series 3 – ZMD310AT/CT

Communication
AT/CT-type meters are equipped with modular
communication units which provide the right choice
for the best data channel at all times. «Plug+Play»
modules also offer you full freedom of choice for
deployment of new communication technologies.
Installation support
The monitoring of voltage, current, demand and
power factor supports the installation.
