3CT Zigbee Energy Meter

SKU: SEM-4-3-20_70A, SEM-4-3-20_120A
Measure the consumption of multiple electrical circuits

Designed for single-phase and three-phase residential and commercial installations, the 3CT Energy Meter provides highly accurate measurements of the consumption or generation of each phase in an electrical circuit, providing data on instantaneous power, cumulative energy, and many other parameters.

Ideal for both new installations and renovations, the module clips into a single DIN slot (18 mm), while the snap-in current sensors allow for quick installation without requiring any work on the wires.


Real-time monitoring

Measurement of current, voltage, power and energy.
Bidirectional measurement

Precise measurement

High precision energy measurement with 1% tolerance.

Over The Air (OTA) update

The Smart Energy Monitor is quick to update thanks to its OTA function. Updates can be made via a compatible home automation system

Ultra Compact Profile

Installation in electrical panels

Compatible with most Zigbee Gateways

This sensor is 100% Zigbee 3.0 interoperable

Monitoring consumption and production in a solar installation

In a house equipped with photovoltaic panels, a bidirectional meter measures the electricity consumed from the public network, and the electricity injected (surplus solar production) into the network.

With my 3CT Zigbee Energy Meter, I can:

Track my electricity consumption

Save money

Do load shedding in case of overconsumption

Distribution of energy costs in a shared building (coworking, apartment building, etc.)

In a building or shared premises, each area or office is equipped with a Zigbee meter on the electrical panel for monitor the individual consumption of different tenants or services, automate load distribution, and identify the energy-consuming behaviors for awareness or improvement.
